Simple integration problem

  1. Sep 7, 2011 #1
    1. The problem statement, all variables and given/known data
    Find the area between f(x)=(x-1)^3 and f(x)=(x-1) on the interval from 0 to 2.


    2. Relevant equations



    3. The attempt at a solution Working it out Im using the top function minus the bottom function from 0 to 1 and then from 1 to 2. The graphs cross at x=0,x=1,andx=2.
    Im geting - (1/2) for my final answer and the answer is 1/2. It's been awhile since if done any calculus so I dont know why my answer is the wrong sign.

    You took the wrong functions to "top" and "bottom". Plot them to see.
