Double integrals over General Regions. (HELP PLEASE !!!!!)

Use a computer algebra system to find the exact volume of the solid.

Under the surface z = x^3 * y^4 + xy^2

and above the region bounded by the curves y = x^3 - x and y = x^2 + x for x >= 0

How do I use a computer algebra system to find the volume.

Do you want the algorithm to find the limits for you then solve it? Or do you require the user to know the limits etc...

The limits for X is 0 to -1 and for Y it's -.25 to .4

Do I need a TI-89 to do this problem.

First, simple solve the integral by hand to get a check value against the computer system.
