# What is the derivative of #sinx/(x^3-2x)#?

##### 1 Answer

#### Explanation:

The first important thing to notice here is that your function is actually the *quotient* of two other functions, which means that you can use the quotient rule to differentiate it.

More specifically, these two functions are

Your function can thus be written as

The quotient rule tells you that you can differentiate a function that is the quitient of two other functions by

Another important thing to remember is that

So, the derivative of your function

This is equivalent to
