add differentiation methods (using taylor series and interpolating polynomials)

[MMDPROJECT]

Note: differentiation_with_interpolation.py will be edited by tomorrow to give 100% percent accuracy for polynomials.

the inf loop in the diff with interpolation

and don't draw plot for both of them

• Inappropriate choice of h will cause the Differentiation process to take so much time. There is no infinite loop.
• Plotting is not that much relevant to the Differentiation methods. But I will add printing the actual result after the approximation has been done.
