Abstract
A method of graphically representing mathematical expressions in both audio and visual formats on a user device is described. Embodiments of the present invention include an Internet-enabled audio-visual graphing calculator that receives input from a user device in at least one of at least one of audio, visual, or Braille formats. An embodiment of the present invention interprets input received from the user device as a typeset mathematical expression, parses the typeset mathematical expression into an interpreted mathematical expression and compiles the interpreted mathematical expression into an evaluation function. At least one point is sampled on the evaluation function. The sampled evaluation function is rendered as a graph on a visual display of a user device. In an embodiment of the invention, an audible representation of the rendered graph is generated for playback on the user device.
