Draw curves that follow defined equation curves:
The math tool set lets you draw curves that are defined by common mathematical functions like parabolas, exponentials, sine waves, and many others (40 variations in all). The tool set is shown on the screen shot the 4 x 10 tool palette upper left of the drawing area.





New (Version 3) axis tools:
Special graphic tools available for drawing axes tick marks and labels. The tick mark tool encapsulates several interactive controls to make it easy to get a desired appearance and look, even two log scale presentations. Separately draw and configure labels for the chart. Your chart labels have the full OS X font and fontface interface for quality presentation graphics as you would expect on your Mac. Easily adjust the spacing, orientation, tilt, and more.





Grid tools:
At the bottom right of the technical tool palette notice two grid tools. One draws free form rectangular grids with numerical or interactive adjustment of spacing. The other draws an interlocked hexagonal (honeycomb) grid which has adjustment for spacing tilted axis and extension adjust for snowflake or a isotriangular grid. Many uses, including game charting.





Many uses  even if you are not a geometry teacher:
These are the equations and proportions of nature. For example the Hyperbolic Cosine (the light blue curve shown in the screen shot below) is the equation for the shape of a free hanging uniform cable. It is called the Catenary Curve, Notice how its use gives the simple sketch below the realistic look of a suspension bridge.





Easy to create, orient, and edit:
These elements are created, sized, and oriented with one mouse motion, clickdragclick just like our rotated oval. Compare this with the effort required to draw the heart beat waveform shown below using free hand techniques. When appropriate additional control handles are provided for direct on screen interactive editing of the precise shape and configuration of the curve. Our graphicdetails drawer (shown in the screen shot to the right of the drawing canvas) is always available for exact numerical specification of the curve.





Details on functions available:
The following is a list of the mathematical functions available on the Math Tool Set. Many functions exhibit Mirror Symmetry, y(x) = y(x). In these cases two version of the tool are needed because rotating the graphic may not provide the shape or orientation desired.
