MathGraphAppLite is a graph-centered calculator.
Your formulas show up as curve immediately after successful compilation.
Tap the graph and move the pointer, the graph will follow your movements.
Variables are ‘global’ and used by any formula. Generate new variables automatically in formulas.
Animate or show curve families by selecting a variable.
Shows Points of interest (minima, maxima, inflection points,…) by selection of a curve.
Scaling and Mapping of x and y-axis inclusive user defined formulas.
Input of numbers by gestures or formulas.
Use of Greek letters in formulas possible
Easy data import from clipboard of data text file.
The App starts with opening last session.
A description of the graph, variables and formulas is provided.
Some features (save, print,…) are not implemented in this freeware version.
