  Derivatives of sin x, cos x, tan x, e^x and ln x | Product and quotient rules | Khan Academy
  
  Here is a proof of the derivative of sin x. d/dx (sin x) = lim h→ 0 (1/h) [sin(x+h) - sin (x) ] _by definition of derivative_. _Using the angle sum identity: sin(x+h) = sin(h) cos(x) + cos(h) sin(x)_ d/dx(sin x) = lim h→ 0 (1/h) { sin(h) cos(x)+cos(h) sin

We’ll use three relations we already have. First, tan A = sin A / cos A. Second, sin A = a/c. Third, cos A = b/c. Dividing a/c by b/c and canceling the c’s that appear, we conclude that tan A = a/b. That means that the tangent is the opposite side divided...
