Functions and Equations

Easy to use, intuitive program to visualize and study functions of one variable in a defined interval to find roots, maxima and minima, integral, derivatives and plot a graph. You can predefine constants and specify the error bound for the results. It can fully explore intervals to search for multiple solutions. Handles trigonometric and hyperbolic functions among others. Results, including the graph, can be saved or printed. You can also copy the graph to the clipboard, which you can then paste where you please (Word, Paint, etc.). You have one-click control of the graph with zooming, panning, centering, etc. Includes a help file with instructions, example and methodology. Numerical computation of definite multiple integrals. You can predefine constants and specify the error bound for the results. Handles a wide variety of functions, including trigonometric and hyperbolic. Numerically solves systems of simultaneous nonlinear equations. It can fully explore defined intervals to search for multiple solutions or quickly find solutions starting with random seeds. You can predefine constants and specify the error bound for the results. Handles a wide variety of functions, including trigonometric and hyperbolic. Numerical approximation of first and second order partial derivatives. You can predefine constants. (Source: http://mathres.kevius.com/software.htm)
