Newton's Method - The instructor, using a stationary camera and a small whiteboard, discusses the basic idea of Newton's Method and how to use it. The instructor does one example using Newton's Method to approximate a root. (07:29)

Function Inverse Example 2: f(x)= (x + 2) squared +1
This is a another installment of Mr. Khan's short 4-part series on Function Inverses. Mr. Khan uses the Paint Program (with different colors) to illustrate his points. Sal Khan is the recipient of... the 2009 Microsoft Tech Award in Education. The screen gets busy (and dark)--the viewer may want to open to 'full screen' to see everything. The sound is a little low.

Function Inverse Example 1: f(x)= -x+4
This is a continuation of Mr. Khan's Introduction to Function Inverses. Mr. Khan uses the Paint Program (with different colors) to illustrate his points.

Function Inverse Example 3: f(x)= (x - 1) squared -2
This is the last segment of Mr. Khan's short 4-part series on Function Inverses. These installments started with Khan's Introduction to Function Inverses. Mr. Khan uses the Paint Program (with dif...ferent colors) to illustrate his points. Sal Khan is the recipient of the 2009 Microsoft Tech Award in Education.
