I have a quick question to ask. How do you find the angle for the bottom angle ( as in the one that goes only up to 0 to pi(which is max).
I had a look at the solutions for this one apparently it goes from 0 to pi/4
find the volume of the smaller of the two regions bounded by the sphere x^2+y^2+z^2=16 and the cone z=sqrt(x^2+y^2).
thanks(im sorry if this looks familiar ..i def have not asked the above issue before)
