R is the region in the first quadrant enclosed between y=x and y=x^3



Homework Equations





The Attempt at a Solution



I set up the bounds as follows: [tex]\int_{x=0}^1\int_{y=x^3}^x x-1 dydx[/tex]

Integrating, I get -7/60, verified with CAS.

I thought this was an easy problem but my answer doesn't match the textbook (-1/2 but could be a misprint, right?) or did I somehow put the bounds of integration wrong?
