a Riemann Sum
how to compute change in x in a Riemann Sum
(b-a)/n
what is b in a Riemann Sum
B is the furthest point to the right on the x axis that you are computing
what is a in a Riemann Sum
A is the furthest point to the left on the x axis that you are computing
what is n in a Riemann Sum
N is the number of rectangles you will divide the graph into
what is the formula for Riemann sum
