Photon is a fully functional graphing calculator capable of numeric calculations as well as graphing functions, including parametric and polar graphs.
In addition to regular graphing, Photon can plot integrals, first and second derivatives, tracing, animation, matrix math, and degree / radian mode. Photon can find roots, minimums and maximums, points of inflection, and it can fit several types of best fit lines and curves to data sets. Log and semi-log graphing are also available.
Photon can save data to several file types, including images such as .jpg and .png. Display options are also available, including a dark / light theme for optimal visibility from a projector.
Photon's primary goal is to be easy to use while retaining a feature-rich design. VB Gadgets brings you Photon - a parametric graphing calculator.
