Hello, I need to find the volume between the plane z=1 and z=10-x*x-4*y*y.
I have tried using polar coordinates:
first integrate from z=1 to z=10-x*x-4*y*y
The I integrate in the plane z=1, but here I need to integrate over an ellipse, how do I do this? When I wrote the expression to polar coordinates I got an expression for r that I couldn't integrate.
I have also tried integrating over the ellipse using cartesian coordinates, but I got stuck aswell, can someone pleas help?
