Integrating an absolute function

  1. Apr 29, 2010 #1
    1. The problem statement, all variables and given/known data

    1
    ⌠ | 10^(1/2)*(x^5)+(5*x^(1/5)) | dx

    −1

    2. Relevant equations
    once the absolute value is gone you can just integrate the function

    3. The attempt at a solution
    how do you get rid of the absolute, and how do you then integrate it, do you use the product rule with 10^(1/2)*(x^5)

    Notice the function inside the absolute value signs is an odd function and is positive if x>0. So its absolute value will be an even function. So double the integral from 0 to 1.
