Description
TouchPlot is a powerful grapher with a long list of features :
formula editor with custom keyboards along with prettyprint display of the formula being entered. Since version 4.0, an alternative algebraic formula editor is provided, and the learning curve is now much lower.
symbolic differentiation
numeric integration with graphical display
user-defined, easy to manage, libraries of functions
representative curves of functions with a focus on accuracy and speed, with several modes for inspection (zeros, extrema, intersection and values, definite integration)
calculation of first terms of iterative sequences, and graphical representation of them
parametric curves in cartesian and polar coordinates
(numerical) solutions of ordinary differential equations (first and second order) with vector fields
user defined constants with sliders to observe how a curve is changed by a parameter, or to adjust initial conditions of a differential equation particular solution...
logarithmic scales if needed, adjustable separately for horizontal and vertical axis.
drawing of equations, inequations solutions, contourplots, gradient fields, and 3d-plotting of surfaces with equation z=F(x,y).
