Homework Statement
Find the volume between 2 paraboloids.
Homework Equations
z = 4x^2+8y^2
z= 30-x^2-y^2
The Attempt at a Solution
So I switched the variables to polar coordinates.
z = 30-r^2
z=4r^2*sin^2(θ)+8r^2*cos^2(θ)
Now I want to solve for r. However I get a very ugly looking value for r that does not integrate very well.
