##### 1 Answer

#### Answer:

#### Explanation:

Take two functions.

E.g.

The product of those functions is:

When we talk about derivatives, the product rule can be used to write the derivative of said functions. Using the functions from before, it states:

In your formula, we can see the "

[Here we use the fact that we calculate each part seperately

and leave the constant, e.i
