Finding T8 and M8 approximations for integral of cos(x²)dx

[pureouchies4717]

hey guys... i kinda forgot how to do this

question is: find the approximations T8 and M8 for integral of cos(x^2)dx from 1 to 0

now my question is whether or not that 8 means that n=8

and also, is this right?

id do the following:

n/2[f(0)+f(.2)+f(.4)+f(.6)+f(.8)+f(1)]

and id use the degree mode on my calculator

is that how i set it up?
