# How do you differentiate #f(x)=e^(-x^2-2x+1) # using the chain rule?

##### 2 Answers

#### Explanation:

The chain rule basically says

So in this case let

Then

You can do it another way using the chain rule more indirectly, based on the properties of

#### Explanation:

The derivative of

This is why the derivative of

However, when you have embedded functions, you have to do more complex differentials with

In the case above, you have

and multiply by
