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
The Quest
Existence of Inverse Functions Not all functions have corresponding inverse functions
Existence of Inverse Functions
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
Properties
Derivatives of Inverse Functions Let. How to find ?
Derivatives of Inverse Functions
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 )
Remarks
Example 1
Example 1: Step 1
Example 1: Step 2
Example 1: Step 3
Expectations
The steps are designed to conform with standard presentation, and minimize the chance of making mistakes. In the exam, I will look for the expected steps.
