TI-83 root question

[Echo 6 Sierra]

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

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