# The formulas are: the derivative of xn is nxn -1, the derivative of sin x is cos x and the derivative of the exponential function ex is itself. The rules are: (af +

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:

Tap for more steps To apply the Chain Rule, set as . 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 trigonometric limits we derived in another section.

### What about the derivative of the sine function? The rules for derivatives that we have are no help, since $$\sin x$$ is not an algebraic function. We need to return to the definition of the derivative, set up a limit, and try to compute it. Here's the definition: ${d\over dx}\sin x = \lim_{\Delta x\to0} {\sin(x+\Delta x)-\sin x \over \Delta x}.$

The inverse trigonometric function are represented by adding arc in prefix for a trigonometric function, or by adding the power of -1, such as: Inverse of sin x = arcsin(x) or $$\sin^{-1}x$$ We’ll start with finding the derivative of the sine function. To do this we will need to use the definition of the derivative. It’s been a while since we’ve had to use this, but sometimes there just isn’t anything we can do about it. Here is the definition of the derivative for the sine function. From above, we found that the first derivative of sin^3x = 3sin 2 (x)cos(x). So to find the second derivative of sin^2x, we just need to differentiate 3sin 2 (x)cos(x).
