1. Derivatives By Mendy Kahan & Jared Friedman

2. What is a Derivative? Let ’ s say we were given some function called “ f ” and the derivative of that function is “ f` ”. f` represents the slope of the tangent line to the graph at point x. This is represented by:

4. Chain Rule This can also be written as: This rule should be used for difficult problems involving composite functions The derivative of this composition is given by the formula:

10. High Order Derivatives For more examples: http://www.exambot.com/cgi/topic/show.cgi/math/difc/diff/hder The rules for taking higher order derivatives are basically identical to taking a regular derivative. Once you take the first derivative of the answer repeat this process as many times as necessary to find the nth derivative. However, there are sometimes patterns and it would be very time consuming to take higher order derivatives. Ex:

11. Higher Order Derivative Ex: Find the 7 th derivative 1.Find the pattern of the derivatives of sin x 2.The pattern repeats every 4 th derivative so: Since the remainder is 3, the 7 th derivative of sin x is the same as the 3 rd derivative.
