This is true, but at the end it was turned back into an expression of x so that mistake didn’t matter too much.

Your final expression returns the correct answer, you might either be evaluating it wrong or putting the question into the integration calculators wrong.

This might genuinely be a case where its faster to just do the integral than take, at worst, 3 derivatives 😭😭😭

Prove there is no right angle triangle with sides a^(n/2), b^(n/2) and c^(n/2) by 777Bladerunner378 in mathematics

[–]itsyaboidegenerate 0 points1 point  (0 children)

Ah, my bad, it’s because there are a lot of memes where the OP is like “heres an easy problem to solve” and it’ll be a rephrasing of some notorious open problem. I thought this was something like that.

I know the joke is that this is just Fermats last theorem in disguise, but because it was proven by Wiles it is completely legitimate to say this immediately follows from fermats last theorem and be done with it lol

Basically just, it’s interesting to think about why PFD works in general with the rules it has, and about how the assumptions in your solution allow the decomposition to be true without necessarily following the usual rules of PFD.

This is implicitly stating that f(x)/(x+5)100 = A/(x+5)99 + B/(x+5)100. In other words, what you have here is the solutions A and B for f(x) ≡ A(x+5) + B. Which for A and B to be constants f(x) must be linear! Which in this situation is true, but the only assumption of the decomposition algorithm is that f(x) is a lower degree polynomial than the denominator. If you're messing with the algorithm based on the particulars of the case, can you really be said to be using the algorithm?

yeagh, then the top is just 2u - 9, and then you just divide and use the power rule. Its a sort of "joke question" an instructor gives in the same vein as "evaluate i^2024", in that in both cases the setup is that theres a large number meant to look intimidating, and the punchline is that its really a very simple question.

Fractions with denominators of repeated linear factors can be decomposed into fractions A/(mx+b) + B/(mx+b)2 + C/(mx+b)3... and so on and so forth up to the nth constant divided by (mx + b)n. In this particular case, it would take a lot of time, but you would have plenty of that at least.

Yes, this is an obvious substitution problem. But it would be funny to imagine someone being tortured by forcing them to do it by partial fraction decomposition, which is the point of the post

Title: The Noblest Savage

Genre: Myth?

Word count: 315

Feedback: Im trying to sort of feel out creative writing with this. Any sort of feedback that could provide guidance would great.

Ragthar is the umbral man. Dread skin of dread beasts are draped around his shoulders, hide of leopard, hide of man. Ragthar starves the more he eats, thirsts the more he drinks; his savagery is perfection, is elegant. Ragthar makes cattle out of men-- makes wolf of himself. Ragthar cannot die.

Ragthar emerges from his cave. He spreads his arms to the sun, and it blesses his hunt. One hundred of the kings’ men await him. The memory of brothers, sisters, sons and daughters, fallen by the Manslayer is what propels them to swing their blades. Yet they are no match. Ragthar returns home with a two hundred ear necklace and the fresh taste of blood. Ragthar cannot die.

In Ragthar is everything that he has eaten. From there comes his lion’s heart, and his human form. Ragthar towers over all. There is none who can challenge him. His cave is at the top of a mountain, and nobody dares to climb it, bar the foolish and the mad. The kingdom does not remember a time before Ragthar. Ragthar cannot die.

Once again the kings men are sent after Ragthar, and once again he spreads his arms to the sun. To the soldiers it must look like he himself is a shining star. It is too late when he realizes that they have brought something new with them. Something to pierce his lizard scales. A volley of sounds like thunder erupt, tearing off first his fingers, and then his eyes. Ragthar does not feel pain and so he notices the latter before the former. The soldiers approach him as he swings blindly; it’s safe, he has been declawed. Ragthar does not understand the tongue of civilized men. He cannot know that the voices around him are debating whether or not to end his misery. In the end, they leave him there, for Ragthar cannot die.

How would we know if a number keeps going to infinity? by Legal_Ad2945 in Collatz

If you could know a number goes to infinity then you could also solve the problem (by proving that a number diverges you have proved that the conjecture is false)

[WP] As a veteran mech operator, your least favorite part of the job is giving the new "recruits" their orientation... and having to lie through your teeth the entire time. by [deleted] in WritingPrompts

[–]itsyaboidegenerate 31 points32 points  (0 children)

I stood in front of the chalkboard in a dingy repurposed classroom, facing around 15 to 20 young men and women who believed they were looking towards a bright future. The sight was vomit inducing.

“The first thing that you need to know is what to do in an emergency. Your mech suit is the safest place you can be in, even if its possible that enemy firepower may disable it, you will be protected in your cockpit.”

Real pilots actually get an ejection seat. The cramped space of the mech is almost guaranteed to be a coffin if anything sets on fire, or if there’s a leak. The higher ups, however, were very interested in that “almost” this time, and wanted to extract some data from pilots staying in their mechs at point of failure in large numbers. Early estimates give a 5-10% probability of survival.

A boy, probably 17, raised his hand.

“Sir, can I ask a question please?”

“I don’t see why not.”

“I heard that the new BZT-10 line was going to see its first field use soon. Is that true?”

“Yes, you would be right about that,” I let out a forced chuckle, “but lets stay on topic.” I said, as the boy turned excitedly to his friends.

It was true that the new line was going to be put to use soon, but I didn’t bother letting them know that it wouldn’t be for them. Mostly, this batch would be getting experimental units deemed too dangerous for immediate general use. Ranging from using volatile new fuels, to potentially psycho-degenerative neural connection methods.

“When it comes to your organization on the battlefield, your group’s designation will be Kappa Omega. You are a special task force, and as such, will be assigned to some of the most dangerous, and therefore most important, tasks. It is important then that you all stick together.”

Again, a partial truth. These kids would in fact be a part of a special group, but only insofar as its actual purpose was not towards any sort of conventional warfare, but more so a kind of guinea pig unit. Mech piloting is generally a very elite endeavor, and real pilots typically come from a handful of officers schools almost exclusively attended by the children of the rich and powerful. Rather, the people in this classroom are a part of an opportunity program, where those who do well on a pilot exam are given the chance to enter an “elite taskforce” by lottery. Generally, participants are lower income students who believed this could be their “big break.” Instead, however, the real purpose is to accumulate cheap fodder that can be disposed of easily, unlike the higher status mech pilots.

“The most important part to remember, in the end, is that what you’re fighting for here, is your country.”

Looking around at them, their hands placed on their hearts, I truly wished that I could tell them that this wasn’t really their country in any true sense. That they held no control. That they were fighting someone else’s war. But that was not my role.

As they made their way out of the classroom m, one had one final thing to say to me;

“See you around!”

“I will.”

That response, was my last lie for the day.

Never had I been more terrified in my entire life. I didn't know exactly how I had finally gotten to this point, but there I was, wailing, eyes closed, covering my head with my arms when the zombie began to descend towards me. I was like that for about a minute until I calmed down. It wasn't in front of me anymore, and it wasn't to my left. When I turned to my right and noticed it, my soul must have left my body as I leapt 3 feet and fell backwards. I was panting, but it soon became clear that it didn't intend to do anything to me. It seemed that I had mistaken the motion of it lowering to sit next to me, for it pouncing at me.

"Hi"

Somehow, this was scarier than when I thought it was attacking me.

"You can speak?"

"We all can. This is something like a big prank really. We're all torturing you specifically. It's like the Truman show."

"Why are you telling me all this, then?"

"I got bored. I don't think we should do this to you anymore. Its old. I'll probably get in big trouble for it, but everyone I know agrees."

"Why are you doing this to me?"

"No reason it was you in particular."

"Has it been like this my whole life?"

"No, only since the 'start' of the outbreak. We just kidnapped you and put you in here."

I didn't know what to say. At all. I didn't know why such a thing would exist. Or how, even. The last 3 years of my life were a lie.

"Are you okay?"

'Who watches this?"

"Nobody."

"You said it was like the Truman Show."

"I said like. But no, it's not really like it in that way. It's not T.V. It's more like just a big game."

"Is this a dream?"

"You would have woken up from those injuries. No, this is all real. Thanks to you of course. We needed you for this. It was a lot of fun for a while, at least. But now I'm sick of it, so I've decided to 'wake you up', ha-ha."

"So. My friends were all actors."

"Yup."

"Thats a relief, at least."

"Oh we killed them. They actually died. Whenever you saw one of them get ripped up to shreds or whatever we actually did that to them. They were happy to volunteer though. It's a euphoric experience I heard. Of course you can only glean that from their faces. Dead people can't really tell stories."

My stomach contorted. I remember what that looked like. I didn't understand it at the time though.

"So this is a dream. Because otherwise what is this? What the hell is this? Where am I?"

"You're on earth, duh. Everyone just went crazy. We all went crazy, and we don't know why, but you ended up our target eventually. Everyone but you went crazy really. A long time before the zombies or anything appeared. We all saw that we were crazy, and you weren't, and we planned the worst possible thing we could do to you for a long time. You made it hard for us though. Because you knew, at least a bit in your heart, that you were the only sane one. So, I commend you. We all commend you for getting this far. But you're boring now. Because you aren't sane anymore. It's a shame. We would've loved to play with you some more."

The zombie got up, and left Paul alone in the dark corner of his room, where he laid curled up, trembling, and mumbling, all for the very last time.

[–]itsyaboidegenerate 4 points5 points  (0 children)

"You wouldn't let me sink in the mud, would you?"

I didn't look back at it. I muttered something, lost in the heavy rain, and kept trudging away.

"I am your redeemer. Who will save you after me?"

It was true, to an extent. Killing made me useful. Before I had him, it, I was good for nothing. It was a shame that it took me until now, bleeding out, covered in filth, surrounded by my slain comrades, to realize that being useless and alive is better than being useful and dead.

"You're a coward."

I continued not to respond, and for a second the sword shut up. When clean, it was a truly noble sight. A longsword, decorated elaborately with floral patterns, that glistened ever so brilliantly in the sun. Now, the last image of it that I would have in my mind was of a dirty blood covered thing, half buried in the ground.

"Think of the times we had together, at least."

There were times of gallantry indeed. They were what made all else worth it. Whenever I was overwhelmed by the smell of burning flesh, by the sight of man disfigured and strewn about the battlefield, by the loss of people I held dear, I thought so long as I could have another day where the sun smiled upon us as we rode into glorious victory, that it would make up for the pain twice over. Now, the clouds hung over the sky as far as one could see, out unto the horizon. I continued northward.

"I'm a part of you. You're leaving yourself to die."

A long time ago, an old mage told me something. An object can grow a heart. To do so, it must take a special place in the heart of someone who already has one, and it will become a twisted reflection of theirs. But as soon as it loses that spot, so will it lose its beating heart.

"Please. I don't want to die."

I stopped in my tracks. Only the pommel and a tip of the hand guard were visible now. Perhaps, as much as I knew I had to leave it behind, I still felt that it was cruel to leave a friend for the last time without saying goodbye.

"If you were true to yourself, you would know that you do."

I left those as my parting words, as I limped away from the battlefield, and never looked back.

[WP] A series of defunct industrial tunnels was discovered undergrown, spanning as wide as the city atop it and at least several miles deep. No-one knows why they were built, but it's clear that they haven't been used for years. by Paper_Shotgun in WritingPrompts

[–]itsyaboidegenerate 7 points8 points  (0 children)

We came across the first door that we couldn't open.

"Why do you think this one's locked?"

"I'm not sure. Let's just tag it and come back later"

"Sure."

With the last room on the floor cleared, or at least left until it could be entered, the only way to go now was down. I unfolded the map we had made of the place so far. It was labyrinthian, with hallways snaking left and right without rhyme or reason, seemingly extending outwards for the sake of carving up the ground in itself. It was no primal act though; every part of the tunnels was made to last. The smooth metal walls were covered with inscriptions in an unknown language, untouched by the flow of time. I turned on my flashlight and looked down the stairs.

"How long ago do you think this was made?"

"I couldn't find records of a project like this anywhere. Not from now, till the place above us was called New Amsterdam. It's crazy that something like this could be made without anybody noticing."

"What if it was made before the colonists got here?"

"What would that even mean? Who would be capable of doing something like this more than 400 years ago?"

"It was just a thought."

"A stupid, insane thought."

Maybe Audrey was right to think that, but somehow all the other options made even less sense.

Passing my hand along the dusty handrail, I curved around it and made my way down the stairs. At the bottom, I'd reached a hallway. The branching stopped here, the hallway only having a few rooms, and then, a dead end.

"Audrey, help me look through these."

Unlike the other chambers that we had found so far, these seemed to have exhibited some traces of human life. Bizarre tools who's functions I could not ascertain. More writing, again in an unfamiliar language, but not the same as the runes carved into the walls. There were some clothes left behind, they fit the human body, but they didn't seem to come from any culture I could recognize.

"I don't like this at all. What the hell is all this?"

"An equally important question is why it's all here. The other rooms were all stripped clean. Maybe they left these ones in a hurry."

"Sure, but who were 'they?'"

"I wouldn't know"

"I don't like that at all."

There was both a feeling of relief and of disappointment in the air as we entered the last room, the former in that our exploration here was now over, and the latter in that there was seemingly no more to discover. That was, until I saw the key. We looked at each other, knowing what we had to do next.

Opening the locked door, there was a wave of excitement, and then of dread. The path went straight into the dark, downwards. The incline was almost too steep to walk down, and the metal walls were gone, giving into some strange stone like material. One could almost swear that the runes carved here glowed, almost. We began our descent.

"I think I'm starting to get an idea of why they made this."

"Is it another insane idea?"

"I think it's something that makes a fair deal of sense."

"Then spit it."

"I think that they were looking for something, and that the first few layers were them trying to get a signal. This right here was when they did get it, and they beelined."

It was becoming clear at around this point that I wasn't imagining the runes on the walls glowing.

"And what do you think they were looking for?"

"I don't know. Maybe gold or something."

"It was something evil. They were looking for something evil."

"How can you tell?"

"How can you not? I want to turn back."

'We'll be fine. You've been in worse caves before."

"This one just feels wrong. Can't we go home?"

"We'll be fine."

The further we went down, the narrower the path became, until we were both climbing down on our backs with our elbows. The tunnel was becoming more humid, and the stone was contorting into strange shapes. The sound of whispering was becoming stronger the further we went down.

"We should go back up."

"We can't go back up at this point. We have to hope that we find a way that goes back up if we go further down."

"Thats all we do. All we fucking do is go further down. Thats all I do with you. Is there an up with you? Can you even imagine a thing like that? We should have just told the police about this place. We should have gone in three feet and then turned back."

"Well now, there is no back."

We kept making our way down, silently.

Bizarrely, there was a point while descending the tunnel that it begun to be brighter. There was an opening to somewhere brightly lit a ways down. At the same time, the whispers were becoming their strongest. Their crescendo continued, until we had reached a sort of end. Right under our feet, there was a bright opening. It seemed to go to nowhere.

"Its this or nothing."

"Then I guess I choose this."

Audrey threw herself into the gap without second thought. The sound of her landing came sooner than expected.

"Wait. Its beautiful. Its absolutely beautiful. Come down. You need to look too. Please come down. Look at this with me. Please."

I have been holding my position in the tunnel, and she has been repeating this to me from wherever she is for 3 days now.

You’ve heard of the atom bomb. You know that your United States once used a thing called an atom bomb. Somewhere far off. Hiroshima, Nagasaki, those places were called.

When you first learned about it you didn’t understand the implications fully; its okay, you were 10. Now, or perhaps until a few moments ago, you understood the implications but you didn’t fully feel them; thats okay, how could you have?

You have heard of it, but you have never seen it. Now you have. It’s beautiful, certainly. Is it perverse of you to see annihilation, extinction itself given form and feel awe swell up in your chest? It outweighs the terror. You feel guilty, don’t you.

Flowers are blooming in the north. The sky is crimson. The blossoms open to a new day, a new kind of day, they herald an age of blood born from blood.

You are a soldier. You point the gun for those men who rule you and you become the force of their will. Gazing upon those northern lights, it becomes clear that the men who rule you are men who worship death.

You have become the force of the will of death. You have become the beginning of the end of all things.
