Derivative sin x proof

Webplaced on the website homepage. But to actually \see" that the derivative of sine is cosine, one needs a bit of analysis. Here, we write out that proof, as done in class. I hope you nd this helpful. First, appealing to the de nition of the derivative, we see that d dx [sinx] = lim h→0 sin(x+h) sinx h: WebProof of cos(x): from the derivative of sine. This can be derived just like sin(x) was derived or more easily from the result of sin(x). Given: sin(x) = cos(x); Chain Rule. Solve: cos(x) = sin(x + PI/2) cos(x) = sin(x + PI/2) = sin(u) * (x + PI/2) (Set u = x + PI/2) = cos(u) * 1 = cos(x + PI/2) = -sin(x) Q.E.D.
