Functy is described as '3D graph drawing package. It allows Cartesian, spherical and parametric curve functions to be plotted and altered quickly and easily. This immediacy and the vivid results promote fun exploration of 3D function' and is an app in the education & reference category. There are seven alternatives to Functy for a variety of platforms, including Mac, Windows, Linux, Web-based and Android apps. The best Functy alternative is GnuPlot, which is both free and Open Source. Other great apps like Functy are Grapher, GeoGebra CAS Calculator, GeoGebra Graphing Calculator and Graphing Calculator.
Gnuplot is a portable command-line driven interactive data and function plotting utility. It was originally intended as to allow scientists and students to visualize mathematical functions and data. It does this job pretty well, but has grown to support many non-interactive...
With Grapher, you can graph equations and data sets and visualize the results on your Mac in real time. Grapher displays algebraic relations, both implicit and explicit, in 2D and 3D. You can use a variety of coordinate systems and choose from a wide array of mathematical...
Free online algebra calculator from GeoGebra: solve equations, expand and factor expressions, find derivatives and integrals
Interactive, free online graphing calculator from GeoGebra: graph functions, plot data, drag sliders, and much more!
Graph functions in two, three, and four dimensions, explicit, implicit, or parametric. Graph inequalities, contour plots, density plots and vector fields. Use rectangular, polar, cylindrical, or spherical coordinates. Solve equations numerically, graphically, or symbolically.
A mathematical modeling software to visualize and animate implicit and parametric surfaces in 3D and 4D.
A simple plotter and numerical solver, which can plot CSV style plain text files with numerical data separated by whitespace, as well can numerically solve equations and ODEs to generate data and plot them for studying dynamical systems.
