Homework Help: Definite integral help,

  1. May 5, 2009 #1
    [itex] \int_0^1 \sqrt{x} - x^3 dx [/itex]

    How do I evaluate this?

    what does [itex] \sqrt{x} -x^3 = [/itex] ?

    It is [tex]\sqrt{x}+(-x^3) \Rightarrow \int_0^1 \sqrt{x}+(-x^3) dx=\int_0^1 \sqrt{x}+\int_0^1 -x^3 dx[/tex]

    [itex]\sqrt{x}- x^3= x^{1/2}- x^3[/itex]. That should be easy to integrate using the "power rule".
