WebExamples 1: Find the derivative of cos 2x using the cos 2x formula. Solution: To determine the derivative of cos 2x using the cos 2x formula, we will use the chain rule of differentiation and trigonometric identitities: cos 2x = cos 2 x - sin 2 x. d (cos x)/dx = -sin x. d (sin x)/dx = cos x. sin 2x = 2 sin x cos x.

Pay attention derivative. WebJan 5, 2016 · Explanation: what we have here is a function 2x inside another function cos . This is known as a function of a function. If we differentiate cosx we get - sinx. when we differentiate cos2x we get - sin2x but then have to differentiate 2x. This can be written as y = cos2x. ⇒ dy dx = − sin2x. d dx (2x) = − sin2x.2. ⇒ dy dx = − 2sin2x. new gas supply
