Let's find the derivatives of the sine and cosine functions sin x and cos x, where the angle x is in radians.
Below we make a list of derivatives for these functions. Derivatives of Basic Trigonometric Functions. We have already derived the derivatives of sine and cosine on the Definition of the Derivative page. They are as follows: \[{{\left( {\sin x} \right)^\prime } = \cos x,\;\;}\kern-0.3pt{{\left( {\cos x} \right)^\prime } = – \sin x.}\]
2 sin t. 2. , 0).
cos^2x is the same as writing (cosx)^2, so we do need the chain rule. derivative of (cosx)^2 would be as follows: = 2cosx * -sinx [note: d/dxcosx = -sinx]

In this section we'll derive the important derivatives of the trigonometric functions f (x) = sin(x), cos(x) and tan(x). In doing so, we will need to rely upon the
b. The derivatives of sin x, tan x, and sec x are cos x, sec 2 x, and sec x tan x respectively. The derivative of the cofunction of any of them is obtained by adding a minus sign and changing each function in the derivative to its 2020-09-09 2020-11-02 2019-01-05 · The derivative of cos x is −sin x (note the negative sign!) and The derivative of tan x is sec 2 x . Now, if u = f ( x ) is a function of x , then by using the chain rule, we have: Derivative proof of cos (x) To get the derivative of cos, we can do the exact same thing we did with sin, but we will get an extra negative sign.
