Newton Raphson-Non linear

It is a numerical method in solving a system of 2 non-linear equations of x and y

It is a numerical method in solving two non-linear equations of x and y using Newton's method. It plots the two functions to help the user decide which initial guesses of x and y to use. It asks the user the initial guesses for x and y and also lets the user choose what termination criterion to use, whether a specified % relative error or a number of iterations.
