Proof of trig derivatives

WebThe basic trigonometric functions include the following 6 functions: sine (sin x), cosine (cos x), tangent (tan x), cotangent (cot x), secant (sec x), and cosecant (csc x). All these functions are continuous and differentiable in their domains. Below we make a list of derivatives for these functions.
