I have an integral from 0 to 1, of sin(x(adsbygoogle = window.adsbygoogle || []).push({}); ^{2}).

I need to, with n=5 rectangles midpoint approximate it.

I've figured that I need something like i=1 and ending at 5 (right?), and the equation is just sin(x^{2}) Δx

Delta x is 1/5.

Are those the correct steps?

I think that all I need to do....

is... uhh.......... Well, actually I'm not sure how to change x^{2}. Should it be x_{i}^{2}?

If that's true, then I think all I need to do, to midpoint approxy is keep on incrementing i, and I think it naturally gives me a midpoint, right?
