For

*g*(*x*) below, write and use your calculator to evaluate a Riemann sum to estimate*A*(*g*, −4 ≤*x*≤ 4) for the functions below with 16 rectangles. Recall that a Riemann sum does not have to involve sigma notation. Homework Help ✎*g*(*x*) =*x*sin^{2}*x*

General form of a right-endpoint Riemann sum:

Your Riemann sum will need to split into two parts.

*A*(*g*) = 42.25
