# Graphing Calculator by Mathlab v3.1.84

Rating: 3

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.

Free version requires internet connection and contains ads! \$5.99 in-app upgrade to PRO. Contact us if you need multiple licenses for a school or organization.
