1 The Quotient Rule The Quotient Rule is used to find derivatives for functions written as a fraction:

2 Let two functions be given:
Can this be the way to take the derivative of their quotient? WHY OR WHY NOT?

3 To find the derivative of their quotient, we will use a formula (which could be found from the product rule):

4 Let’s restate this rule in words instead of symbols:

5 Now let’s find the derivative of our example using this rule:

6 Now you try one. Differentiate the following function. The answer is on the next screen, but don’t look until you attempt the problem on your own.

7 Use the quotient rule to find the derivative.
Do not simplify your result.

8 Here’s how we could use that answer:
Find the slope of the tangent line at

Complex Functions These derivatives involve embedded composite, product, and quotient rules. The functions f or g must be derived using another rule.
