Return to Assignments Product and Quotient rule

### Assignment 14

Differentiate:

### Solution

This function is not in the list of standard functions. However, from trigonometry we know:

and thus we can apply the quotient rule with:

and:

and thus:

and:

and thus the quotient rule yields:

We can simplify this formula in two different ways. Because:

we can write:

Or, when we rewrite the original function we get the following form:
