3.5 | The Trigonometric Functions


Trigonometric Differentiation Rules:

  • \( \displaystyle \frac{d}{dx}[\sin x] = \cos x\)
  • \( \displaystyle \frac{d}{dx}[\csc x] = -\csc x \cot x\)
  • \( \displaystyle \frac{d}{dx}[\cos x] = -\sin x\)
  • \( \displaystyle \frac{d}{dx}[\sec x] = \sec x \tan x\)
  • \( \displaystyle \frac{d}{dx}[\tan x] = \sec^2 x\)
  • \( \displaystyle \frac{d}{dx}[\cot x] = -\csc^2 x\)
