I dont know how to get the edge of the cone in cylindrical coordinates.
we have a cone starting at the origin, of heigth 2 and the top is a circle of radius 1 (center at the origin).
we want to calculate the volume.
I set the integral
(|(a,b) means integral from a to b)
for theta : |(0,2*pi)
for r: |(0,1)
for z: |(X,2) I dont know how to find the lower bound X
can you help me please?
