We can aproximate the root of the non linear equation with numerical methods like: a. Bisection b. Regula Falsi c. Newton Repson d.
Imagine we have 10 equations with 10 variable, how can we solve this problem? We can aproximate the roots of the linear equations with Gauss Back Subtitution
If we have 2 point data or more, we can find new velue between the data
