how much money did you receive for graduate funding are you in math or physics/masters or phd are you in Canada or the United States or somewhere else and what do you think is average, below average, above average for a domestic masters student per year? how do they make the decision...

what do you think would be most beneficial to prepare for first year of grad school in math e.g. reading journals (or trying to), reviewing undergrad or learning more advanced topics also what can i expect when i get there

good to know thanks

Does anyone know what the acceptance rate is for some Canadian grad schools in either physics or math

could someone please help me understand this proof given in an article by William Miller (attatched) its supposed to follow from the prime number theorem that given, A(x) which is the sum of all primes less than or equal to x and theta(x) which is the sum of the log of all primes...

I've written 2 papers one was more or less an expository on a difficult topic in group theory and the other one I just finished writing is a paper that introduces the basic concepts in elementary measure theory and then gives an original result from it. I submitted the first one to a journal but...

http://planetmath.org/?op=getobj&from=objects&id=4370 that's pretty much the proof of Stolkes Theorem given in Spivak but I'm having a lot of difficulty understanding the details specifically...when the piecewise function is defined for j>1 the integral is 0 and for j=1 the integral is...

hi im a pure math major and going into my sr year next semester im supposed to apply to grad schools sometime next year as well, but I have a problem. I don't think id have a problem getting into a program my GPA is 4.0 in all my math courses and I've taken quite a few including some...

Is there an easy way to compute the residues of cot(piz)f(z) (used in sum of series)

ahh that looks scarry but thanks any insight on how you got it? I was thinking residues but they look really ugly

What is sum n=1 to infinity n^2/(n^4+1)

i tried what you said but i sitill can't seem to find where i went wrong the formula in the text says -pie^(-pia)/sin(pia) SUM residues of fz^(a-1) excluding 0 = Integral -inf to inf z^(a-1)f(z)

I need to compute integral x^(1/4)/(x^2+9)dx from 0 to infinity so I use a formula -pie^(-5pi/4i)/sin(5pi4)SUM residues z^(5/4-1)/(z^2+9) so that's sqrt2pie^(-5pi/4i)3^(1/4)/(6i)(e^(pi/8i)-e^(3pi/8i)) (with the 0<arg<2pi branch of sqrt) but e^(-7pi/4)(e^(pi/8i))-e^(3pi/8i)) which is some...

sorry to anyone who was trying to figure it out...i solved it turns out i substitutes 1/2(z+1/z) for sine instead of 1/(2i)(z-1/z) I make the stupidest mistakes ever and it costs me. anyone know how i can avoid these =(

hi, this is really frustrating because I've been working on this one integral for the last 2 1/2 horus and i can't figure out what I did wrong... it's the Integral sin^2(x)/(3-2cos(x)) dx from x=0 to x=2pi I tried the substitution z=e^(itheta) plugging in sin and cos as functions of z...
