use simpsons's approximation method, it has 100 percent accuracy for this type of problem i think, but make sure to check ur error, just in case.

Use the substitution u=4x-1

so du=4dx

if x=1, u=3
if x=2, u=7

stick them in and integrate the now much simpler expression, and you get 2/21

I think!

Hope that helps,

wow, i overlooked the simplest method, substitution lol. afro was on the right track. with the substitution, and i got 2/21 too. i think u do get the same answer with simpson's approximation though.

oops forgot to update this post.

yes it was substitution integration, figured it out after much stress, finally think im getting my ahead around this module.
