4.1 Homework/Quiz due Tuesday February 2, 2016 Math 121 Section 4.1 Techniques for Finding Derivatives Jan. 28, 2016 We know how to find the derivative of a function using '( ) f (a+h)−f (a) f x =lim ¿h→0 h (provided the limit exists). Let’s find a more concise way for taking a derivative. Notation: There are many different ways to express “the derivative of f at x” ' dy d f (x) [ (x)] [x (x)[] (x)]' dx dx Properties of the Derivative: ' 1. Constant Rule: if
