It should look like this:
Verify that this is the right integral and I'll start working on it.
I have a question about evaluating the iterated integral
its a homework problem i was doing ok with the double integrals but the triple confuse me
int(int(int(x*cosy,x,y,z,0,4,0,pi/2,0,1-x)))
I think that is how you right it well i know it the problem but i was trying to get the signs to actually come up
