Re: MX2 Integration Marathon

This is a double integral over a keystone shape in polar coordinates. (so limits are finite, and not a complete circle).

I've tried all sorts of things. I am not even sure if there is an analytic solution. Is there away to show there isn't one?
why do you post this, and you can't even do other simple questions?

Re: MX2 Integration Marathon

is there a fast way to do this question?
the way i do it is with complex numbers and it gets really messy.
u can do partial fracts but it takes bloody ages
