Part I: Review of the Inverse Functions Quick review (Read the text carefully if you do not remember the details) Part II: The relation between the derivatives of a function and its inverse function
6
The Quest
9
Existence of Inverse Functions Not all functions have corresponding inverse functions
10
Existence of Inverse Functions
11
Not all functions have corresponding inverse functions In order for an inverse function to exist, this situation cannot happen: Two distinct points have the same function value
12
Properties
13
Derivatives of Inverse Functions Let. How to find ?
14
Derivatives of Inverse Functions
18
Remarks The formula can be written equivalently as which we are going to use in later sections ( and it is easy to remember due to the wonderful design of the notations )
