Programming TI-83 for Reimann Sums: Y1=\sqrt{1+sin^3}

[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

I understand your frustration with programming the TI-83 for Reimann sums. To input the \sin^3 function, you will need to use the ^ button, which is located above the divide button. To do this, press the ^ button, then type in 3, and then close the parenthesis. This should give you the proper input of \sin^3. Additionally, you may need to use the square root function, which can be found under the MATH button, to properly input the \sqrt function. I hope this helps and good luck with your programming!
