"also a lifesaver"
Response Details:
Push the "MATH" button and choose "fnInt("

Then, it'll simply be in this format:

fnInt([equation],[variable of integration],[low bound],[high bound])

Example:
Integrate the function X2 over [-2,2].  To do this, simply type:

fnInt(X2,X,-2,2)

Press enter and you get the answer.
