Differentiate w.r.t x: e^3x cos 2x

Let y = e^3x cos 2x , z = e^3x and w = cos 2x

Formula :

According to the product rule of differentiation

Differentiate w.r.t x:

Differentiate w.r.t x: e^2x sin 3x

Differentiate w.r.t x: e^-5x cot 4x

Differentiate w.r.t x: cos (x³ . e^x)

Differentiate w.r.t x: e3x cos 2x
