sorry for not using LaTex, haven't used this forum in ages.
And thanks so much for the help! very smart move!
Correct me if I am wrong, the answer is 4i*pi?
Really need help for this one. Cheers!
Homework Statement
Question: calculate function z/(1-cos z) integrated in ac ounterclockwise circular contour given by |z-2pi|= 1

The Attempt at a Solution
Clearly the pole in the given contour is 2pi. But the problem is: if it's a...
let u=y/(a^1.5-x^1.5)^2/3 and v=x/(a^1.5-y^1.5)^2/3
got 0 for this
let u=y/(a^1.5-x^1.5)^2/3 and v=x/y this got really nasty
so i just don't know the trick of findin proper v and u
Homework Statement
Let R be the region bounded by x^3/2+y^3/2=a^3/2 (x>0, y>0) and the coordinate axes x=0, y=0. Express it in double integral over a rectangle.

How to determine if cos(2n)/n^0.5 is convergent?
I've tried summation by parts and other methods but none of them works.
Hope someone can help me. Cheers
Sorry its the sum where n goes from 1 to infinity
