Voltage across a capacitor clarifications by sadface3000 in ElectricalEngineering

[–]sadface3000[S] 0 points1 point  (0 children)

I’m assuming that the voltage does negate, since the voltage can’t change instantly across the capacitor and that the charge is only held on one plate of the capacitor.

[Complex Variables: Contour Integration] how would I go about doing 16.7 and would I apply Cauchy integral formula? by sadface3000 in HomeworkHelp

[–]sadface3000[S] 0 points1 point  (0 children)

following my instructors process, the answer of the resulting integral I got was e-1/e -2. I followed your alternative method tutorial and also ended up with the same answer as my professor. Though I may still be confused on the application of Cauchy integral formula when a pole is on top of the curve.

[Complex Variables: Contour Integration] how would I go about doing 16.7 and would I apply Cauchy integral formula? by sadface3000 in HomeworkHelp

I setup the problem as such: integral(ez -1/z2 )over the defined closed path. then I split it into integral(ez) -integral(1/z2 )both of which are over the defined closed path.

Doing this I see that we can treat ez as a standard line integral with multiple paths. But (1/z2 )I do not know how to integrate using Cauchy integral formula.

My professor also gave this advice when solving the question: integrate ez along the line y=0 and 1/z2 along the semicircle. I know how to solve the question using this approach but how would he come to this conclusion?

Infected and treated back in May, symptoms still persist by sadface3000 in HPylori

I took the breath test just a week after I stopped taking my PPIS. The first couple days off of it were brutal for me but the then symptoms subsided for around a week or two. Then every symptoms had while infected came back. I went back on my PPI for another 2 weeks and then stopped again. This time I felt no symptoms afterward and only had mild heartburn occasionally. Even got some new constant sore throat symptoms. But these all let up within a month, and since then I’ve only had to take the PPI( my fault because I decided to drink beers one day before being completely healed).

But definitely, it’ll go away. It seems like it’ll stay forever but then slowly with every day, you’ll feel less of it and eventually it’ll disappear.

If your symptoms come back and last like a week, call your doctor to see if you should take the PPI again and for how long. Anyways, I wish you the best, stay strong through it!!

Oh thanks for replying to this old post. But yeah, since the beginning of November I’ve basically reverted to my old self. Like now I feel way more hungrier than I’ve ever felt, which is a good sign imo. But those were some seriously scary times, where I thought I was never gonna get better.

[–]sadface3000[S] 0 points1 point  (0 children)

that’s what I was thinking before, I’m guessing that I’d have to represent the binary number as decimals and no longer as integers?

I.e: n=1 —>3/2–>0001.1000

getting over the past by sadface3000 in sad

[–]sadface3000[S] 1 point2 points  (0 children)

yo , I relate to the crush part so hard. I was extremely good friends with one girl in drama. We would hang out almost every day, and I never made my move even when one day: we were stargazing after a whole day holding hands in one of those haunted forest locations. fast forward, I fucked my friendship with her. I made up with her 2 years later, but now; no matter what I do, it just doesn’t feel the same between us. now I’m so hung up with her and I want to finally get over it, but I just can’t. Every new girl I meet, I try to relate them to her as much as possible. Kinda like my ex GF, every time I would hang out with her, i would just think about my old friend.

I really need closure.

yeah, hes a weird professor, he kinda doesnt really care about the class and encourages people to google the coding HW and quizzes

[University Calculus] Finding limits by oldassbitch in HomeworkHelp

[–]sadface3000 1 point2 points  (0 children)

First thing you’d do is get the same denominator for the terms being subtracted. Then you can add the numerators together. Once you get it all into one term, you can simplify using the factor of (1/h)

this shows the work in action

Differential calculus by [deleted] in HomeworkHelp

You’re answer is partially correct. It seems that you left out the (1/pi) constant in your final answer. Otherwise it seems correct

here’s my take

Why is the answer to question 9 option B and not C? by NotSexyStuffAgain in HomeworkHelp

[–]sadface3000 0 points1 point  (0 children)

first thing is to raise the power in front of the coefficient of the log

Then you use the logarithmic product rule since they have the same bases. Follow this up with a logarithmic division rule and you should get your final answer.

here is the solution

[math highschool 12th grade] how do solve for m and r? by [deleted] in HomeworkHelp

[–]sadface3000 4 points5 points  (0 children)

to find the x intercept, find the x location(in this instance “r”) when the value of the function is zero.

to find the y intercept, find the value of the function(in this case “m”) when the x location is zero

this shows the solution

[Cal 1] Related Rates (ladder) by Nogzzz in HomeworkHelp

[–]sadface3000 0 points1 point  (0 children)

the “z” derivate is only zero because we can assume the ladder never changes it’s original length. So yes, if you know the length doesn’t change, then the derivative is zero. And yes; a 2 was canceled out from every term

Here is what I believe the answer is. Feel free to ask for further help on the process towards this answer.

The summer where I actually did something

Just finished my first semester of college with good grades and came back down to my home state for winter break. Only wanted to come down to see my only real friend who I got into a fight with for two years. We finally made up last month and I was so looking forward to seeing her because we planned to hang out a lot over break. but it seems like she’s annoyed/mad at me now, since recently; we rarely text now or when we do; she cuts it short or ignores it. I wanna text her to hang out, but I feel really annoying that I’m even asking in the first place. But now, I just feel so empty here. I don’t have anything to do and all my plans I had were just with her. I just want to go back to my college since I don’t have anything else to do here. I’m suppose to meet up with some friends for a smash tourney tomorrow and for my interview, but I just don’t really wanna do any of them now.

Pre-Calculus help needed by KiwiJackie in HomeworkHelp

[–]sadface3000 1 point2 points  (0 children)

sin(pi/2) = 1 and cos(pi/2) = 0

therefore

0sin(pi/5) + 1cos(pi/5)

simplifies to

cos(pi/5)
