## Tangent Function

Derivative of Tan x Proof by First Principle To find the derivative of tan x, we assume that f (x) = tan x. Then by first principle, its derivative is given by the following limit. f' (x) = limₕ→₀ [f (x + h)

## Derivative of tan(x) (old) (video)

There are half-angle formulas. The one for tangent is: tan (x/2) = ±√ (1-cosx)/√ (1+cosx) Given that sin x = √2/2, and 90
