Question is: evaluate by reversing the order of integration:
int(0-4) int(sqrt(y)-2) (y exp(x^2))/x^3 dx dy
(sorry about the crude way of expressing it, tried my best)
I began by setting sqrt(y)<x<2, etc then got to:
int(0-2) int(0-x^2) (y exp(x^2))/x^3 dy dx
and then to:
int(0-2) (x^2*exp(x^2))/2x dx
could somebody please confirm for me that I am heading in the right direction, and the correct answer will be found when I solve that single integral equation? I've given it a go but to be honest I'm not very confident...
