Lagrange Interpolating Polynomial
This program takes in user inputted x and y coordinates and returns as output the lowest degree polynomial function that intersects all coordinates
The lagrange polynomial can be expressed in either fraction and decimal forms
The output has been configured to allow the user to simply copy and paste the output into the graphing calculator at https://www.desmos.com/calculator
SAMPLE
[(-5.0,3.0), (2.0,6.0), (-3.5,-3.0), (6.0,-5.0)]
f(x)= (-337.0/2926.0)x^3 + (331.0/5852.0)x^2 + (1162.0/417.0)x^1 + (469.0/418.0)x^0
