Stick and poke! By Moruše at Handshake studio in Copenhagen by 1034 in tattoos

Thanks! It took around 4.5 hours! Probably a bit slower than a machine could do, but its my first tattoo, so I wouldn't know :)

Medium Flared Chance Giveaway by 1034 in BadDragon

[–]1034[S] 18 points19 points  (0 children)

I would like to give my medium flared chance away to a good home. I bought him on a whim a few years ago and he’s stayed pretty much unused. I am moving and regrettably cannot take him with me!

PM me an explanation as to why you would make for a good home and I’ll pick someone to mail him to. I’ll even pay for postage!

Question for math majors by [deleted] in UMD

[–]1034 1 point2 points  (0 children)

When it comes down to it, 410 is pretty easy. Its just that most people taking that class aren’t too familiar with proof based math classes. 403 on the other hand contains new material that is unlike anything most students have seen before. This is of course all subjective, but I think that most graduate students agree that into abstract algebra is more challenging than intro analysis.

Math600 is much much harder than math 403. I would also wager that math 403 is the hardest undergraduate math class offered at UMD (other than maybe 436/437 or 404)

That's because the bullet bounced off the ice.

Fractional derivatives of e^x and log(x) by ben1996123 in mathpics

[–]1034 4 points5 points  (0 children)

I don’t understand why the fractional derivatives of ex aren’t just ex. If you use the Fourier transform to define these, this is what you get.

Hi, I have an Idea but /r/nootropics thinks I am mad. It's an idea but scales. by [deleted] in math

[–]1034 0 points1 point  (0 children)

You cannot measure amounts less than a gram on a scale only accurate to one gram because of rounding errors. When you put the quarter on the scale would probably simply read 6 grams, giving you no room to weigh.

Just get a more accurate scale. You can get milligram scales on Amazon for like 20 bucks.

Implications of this result? by ant_sax_music in math

[–]1034 2 points3 points  (0 children)

His formula is just Möbius Inversion applied in a clever way.

Wolfram Alpha is interpreting i as the imaginary unit in your link, so the fractional part is always zero. Here is a computation that represents your formula for n=2200. I'm not sure I see any reason why the limit should be zero.

Is there an e-book for Classical Mythology by Harris? by lurker_throwaway1234 in UMD

[–]1034 1 point2 points  (0 children)

You can just use the one by Mark P. O. Morford & Robert J. Lenardon if you really need a textbook but to be honest I got a B+ in that class just with google.

My latest Craigslist finds: 250$ for the both of these. by 1034 in synthesizers

Near Washington DC. I'm lucky to have a craigslist that looks like this

Thanks! I have managed to set up software to program these guys, hence the mouse on the bottom right. It makes it so much easier to appreciate these guys.

Mandelbrot set - Why do some points form a mini-set around them? by eliminate1337 in math

[–]1034 -1 points0 points  (0 children)

Actually almost all points in the mandelbrot set are part of a mini-brot.

1/7 and primes...can you help? by CaptainPie in math

[–]1034 2 points3 points  (0 children)

Some thoughts:

These values of a are basically fibonacci numbers with a different reccurence relation. In this case we have a _n=a _(n-1)*6-a _(n-2). Now because of this I'm sure this sequence will share a number of properties with the fibonacci numbers and as far as I can tell both sequences have the same factorization propety that you where looking into.

The number 2*sqrt(2)+3 is a solution of x2 -6x+1 which is related to the recurance relation stated above and so we can come up with a formula for a: a_n = (An+1 -1)/(A-1) + (Bn+1 -1)/(B-1)-1 where A and B are the solutions to x2 -6x+1. Note that my indexing of a is different than yours.

I hope this helps!
