3 Videos on Importance of approximation and finding product approximation

Next 3 videos discuss importance of linear approximation as well as finding the approximation for a function which is the product of two functions.
We will cover following issues in these videos-

• Importance of approximation
• Find approximation of a product of two functions
• Find approximation of a product of two functions directly
