derivative of (cosx)^2 would be as follows: = 2cosx * -sinx [note: d/dxcosx = -sinx] Theorem The function sin x is differentiable everywhere, and its derivative is cos x. At each point, the slope of the curve sin x is given by the derivative, namely cos x. Indeed, you can see that when sin x has zero slope cosine has value 0, and so on.

Support any one sign symbols and some functions: exp, sin​,  2. cos(y) = x + y To find the derivative of ln(x), use implicit differentiation! Rewrite y = lnx as e y. = x. Take a derivative of both sides of ey = x to get dy dx e y​. = 1. cos(x).

I prefer to rearrange and use Implicit differentiation as I always get the inverse derivatives muddled up, and this way I do not need to remember the inverse derivatives. If you can remember the inverse derivatives then you can use the chain rule.

If you want to make sure that you get all of the different steps that we're showing, feel free  25 Sep 2020 There are two methods that can be used for calculating the derivative of cos^2x. The first method is by using the product rule for derivatives (since  7 May 2016 See the explanation section below. Explanation: We'll need the following facts: From trigonometry: cos(A+B)=cosAcosB−sinAsinB. Derivative of cos(x)/x by x = -(x*sin(x)+cos(x))/x^2 Copy to clipboard.
