Graphing calculator

Based on Eval

Motivation: Using a real graphing calculator is too slow and awkward.

Result: Plottron is a nice graphing calculator app for your phone.

Features

  • 2D and 3D graphing
  • Multi-touch zooming, panning
  • Polar and spherical coordinates
  • Parametric relations
  • Tangent line from symbolic derivatives
  • 3D augmented reality mode

Languages and Platforms

  • Android (Java)
  • Windows Phone (C#)

Nowadays our phones have high-res screens, 4G, and all the GBs.
So why use a physical graphing calculator from the 1980s?

Apps

Three-dimensional graphing

3D plotting makes it easier to visualize multi-variable functions. Plot standard 3D functions, as well as parametric surfaces.
Apps

Multiple relation types

Express a wide variety of curves with parametric relations and polar coordinate functions. Three-dimensional graphing using spherical coordinates is also available.
Apps

Tracing

Trace graphs to find out more. Use the keypad for exact values. See the tangent line for any point. Find function intersections, roots and extrema. Integrate 2D functions.
Apps

Statistics

Various probability distribution functions are included. Easily find the mean, variance, and standard deviation of data samples with the RPN calculator.
