WebMathematica is well suited to your problem. It supports a number of non-linear solvers and it is great for symbolic computation. Personally with the latest edition of Mathematica I find that I can typically outperform Matlab in terms of both speed and functionality. The documentation also provides a wealth of examples. WebAn equation is linear if its graph forms a straight line. This will happen when the highest power of x is 1. Graphically, if the equation gives you a straight line then it is a linear equation. Else if it gives you a circle, or parabola, or any other conic for that matter it is a quadratic or nonlinear equation.
