Homework Help: Simplifying Integral

  1. Jan 30, 2008 #1
    Here is an integral question I have. It's a surface area problem, but i just have issues simplifying the square root before solving. Any help appreciated!

    y=(1-x[tex]^{2/3}[/tex])[tex]^{3/2}[/tex], 0[tex]\leq[/tex]x[tex]\leq[/tex]1

    My work:

    S=(insert integral with limits here) 2[tex]\pi[/tex]xds
    =2[tex]\pi[/tex]x [tex]\sqrt{-x^{-2/3} +1+1}[/tex]
    =2[tex]\pi[/tex]x [tex]\sqrt{-x^{-2/3} +2}[/tex]

    I'm not sure where to go after this...
