Wolfram Mathematica Online Integrator

yikes.

It may be a change of variables type of limit. You know, something like

Do you have any notes on this? - March 31st 2010, 07:46 PMlauren72
*sigh* No. And I already tried using wolfram. But I think I might have an idea using the second fundamental theorem of calculus... maybe.

Are you taking Real Analysis? Or calc?

I'd evaluate the integral, substitute 2 and 2+h for the t values, and multiply that by 1/h. Then I'd evaluate the limit.

Actually I think I got it figured out... I'm not sure how I did it, but I got the right answer.

Thanks anyway, guys. - March 31st 2010, 07:52 PMSethP
Oh, yeah. It's been a while since I've done limits; my brain sort of gets rid of stuff I haven't thought of in a while.

Yup. And got sqrt(15)

Let be an antiderivative of

then

so your answer is correct
