Original Pull Request: https://github.com/TheAlgorithms/C/pull/1388

State: closed
Merged: No

Description of Change

Added two new files to the numerical methods directory.

File 1: differentiation_midpoint.c -> Uses the symmetric derivative to calculate the derivative for any function at x as long as x is defined

File 2: differentiation_second_mid.c -> Uses the second derivative three-point midpoint formula to calculate the second derivative for any function at x as long as x is defined
