(adsbygoogle = window.adsbygoogle || []).push({}); Use the midpoint rule to approximate the following integral:

∫sin(x) dx

This is what I did:

Δx = (1-0)/4 = 1/4

1/4(f(1/8) + f(3/8) + f(5/8) + f(7/8) + f(9/8))

But the answer i get is wrong. Is that the correct midpoint rule formula, and are the values I plugged in right? Any help is appreciated, thanks.
