Description
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 and parametric equations, inequalities. Displays function values and slopes, roots, extremes, intersections. Algebra, polynomials, polynomial equation solving, matrix and vector operations, fractions, derivatives, complex numbers and more. Shows results as you type. Use navigation menu to switch between modes.
