Integration to calculate centre of mass

  1. Nov 26, 2013 #1
    If you have the function, (1+x3)1/2, find the indefinite integral.

    I have been trying different methods like substitution and rewriting it, but keep getting the wrong answer.

    I keep trying to find it using online integral calculators (http://www.integral-calculator.com/#expr=(1+x^3)^(1/2)) but it's not giving me anything to work with.

    Any help would be great! :)

    Wolfram Alpha can integrate it. It's an unholy mess and has elliptic integrals in it. What problem are you actually trying to solve?
