Taylor Series Exp. 2 Variables with Graphical Representation

This code generates Taylor series expansion for 2 variables and plot the obtained result and the function itself.

This code generates Taylor series expansion for 2 variables in form,
F=F(A,B)+(dF/dx|(A,B))*dx+(dF/dy|(A,B))*dy+...
Where, F is the Function,
A is the initial x coordinate.
B is the initial y coordinate.
The Code needs only 3 inputs,
1. The Function F
2. No of Terms
3. Initial coordinates A and B
This code also plot the obtained result and the function itself.
