Homework Statement
Find the volume of a solid whose base bounded by y=x+1 and y=x^2-1, with cross section of a square perpendicular to x-axis
The Attempt at a Solution
So i set up the problem like this delta volume= y^2*delta x, that being the area of the square where i get loss is that I am supposed to subtract the curves from one another but don't know if its setup like this:
integral from -1 to 2 ((x+1)-(x^2-1))^2 dx or ((x+1)^2)-((x^2-1)^2) dx, from here i know how to do the rest
