Requirements: Android 2.1 and up
Overview:
Graphing calculator with algebra. Essential tool for school and college. Replaces bulky and expensive handheld graphing calculators.
Multiple functions on a graph, polar graphs, graphing of implicit functions, values and slopes, roots, extremes, intersections. Algebra: polynomials, polynomial equation solving, matrices, fractions, derivatives, complex numbers and more. Shows results as you type. Use menu to switch between modes.

* determinant, inverse, norm, transpose, trace
LIBRARY:
* user defined constants and functions (PRO)
* save/load expressions
What’s New:
Logarithms with arbitrary (positive) base, enter base in square brackets, log[2+2](4).
Setting to hide function keys (sin, cos…), makes number keys larger.
