TI-83 root question

  1. Oct 3, 2005 #1
    I'm trying to program my 83 for Reimann sums and I believe I've got it now but to plug in for Y1=[tex] \sqrt{1+sin^3}[/tex] how do I make the [tex] \sin^3[/tex] part because the parenthesis keep me from getting the ^3. I've tried the MATH button but it won't work that way.

    You have to enter it like this:
    sqrt(1 + (Sin(argument))^3)
    Sin^3 is the same as (sin(argument))^3
