This solver is used to find the solution of non-linear equation system. It uses Newton-Rasphson algorithm. The process will start with initial values and will be iterated until it finds the nearly exact solutions that satisfy the tolerance given &epsilon. The iteration process will go with limited number of trials and loops. With each trial the program may return a set of solutions or roots or "not found" notice with that curtain trial run. You can manage to repeat trial as many as you can.

*After several trials with "not found" you should manage to enter initial values!*
