Description:

This applet solves only the real roots of polynomial equations up to a maximum of order five. Complex number solutions are not available, however it can be included in the future if users request such features.

y = ax5 + bx4 + c x3 + d x2 + e x + f

The user can supply the coefficients (a, b, c, d, e, and f) of the polynomial through text boxes.

Comment:Cool equation solver, but it is not clear how it gets its answers. The answers are not in any sort of explicit form, either. Of course, it is useful as a numerical method, but then again, how often is that (for the student)?
