i'll do start the first question for you..
on using right-end-point method.
so,
so the area of the rectangle is
....
do the continuation..
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
