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 Answer link WebHere are some examples illustrating how to ask for a derivative. derivative of arcsin. derivative of lnx. derivative of sec^2. second derivative of sin^2. derivative of arctanx at x=0. differentiate (x^2 y)/ (y^2 x) wrt x.

What is the derivative of cos2x? - Quora
WebDerivatives of the Sine and Cosine Functions. We begin our exploration of the derivative for the sine function by using the formula to make a reasonable guess at its derivative. Recall that for a function f ( x), f ′ ( x) = lim h → 0 f ( x + h) − f ( x) h. Consequently, for values of h very close to 0, f ′ ( x) ≈ f ( x + h) − f ( x) h. WebI want to show that the functions 1, cos ( x), cos ( 2 x) are linearly independent in C [ − π, π].
