Thanks so much.
Q1, use two rectangles to approximate the area contained between the curve and the x-axis.
use the method indicated and give your answer correct to two decimal places.
a, y=1/2xsquared between x=2 and x=3
using the right end point method
b, y=cos x between x=0 and x=pie/2
using the left endpoint method
c, y=1/2xcubed between x=1 and x=3
using the right endpoint method
