Homework Help: Absolute value integral

  1. May 5, 2013 #1
    1. The problem statement, all variables and given/known data

    ∫0-->x |t|dt

    2. Relevant equations


    3. The attempt at a solution

    1/2*x^2 for x>= 0

    1/2*(-x)^2 for x<= 0

    Not sure what to do to be honest. (the answer in the back of the book says 1/2*x|x|).
