Function Graphing in 2D and 3D

3D polar graph

2D Parametric function

The GRAPHING package allows you to draw graphs for nine types of function.

These are functions of the form:-

- z = f(x, y),
- x = f
_{1}(u,v), y = f_{2}(u,v), z = f_{3}(u,v) - r = f(a, b),
- x = f
_{1}(t), y = f_{2}(t), z = f_{3}(t) - r = f
_{1}(t), a = f_{2}(t), z = f_{3}(t) - z = f(r, a),
- y = f(x),
- r = f(a) and
- x = f
_{1}(t), y = f_{2}(t)

The functions can be plotted without or with axes which can be scaled and the resolution of the graph can be changed to facilitate speed of plotting.

Up to 10 different functions of the same type can be overlaid with each being drawn in a different colour.

The 3D functions can be displayed and printed in one of two stereo forms: stereo-pairs or red/blue anaglyphs.

Functions can be stored and any number of different storage files created. There is also an extensive "Help" file included.

The package now allows 3D surface plotting with some forms of graph, courtesy of the Surface Viewer control by Bright Ideas Software
