Tangent Software
Plotting functions (usual and parametric) with more possibilities. Differentiation of any order (with simplification). Construction of tangents to the graph. The simple and clear interface with detailed documentation and examples of work.
CAD Closure allows you to generate geometric closures from the dimension text (not line properties) in your CAD drawing. Works seamlessly with AutoCAD but is not required as CAD Closure has a built-in viewer. Multiple reports formats available.
This graphing calculator can plot y(x), x(y), polar, parametric and table-defined functions. Calculus features include obtaining derivatives, equations of tangents and normals, numerical integration, regression analysis.
Graph is a program for drawing graphs of mathematical functions in a coordinate system. Graphs may be added with different color and line styles. It is possible to evaluate a function at an entered point or tracing the function with the mouse.
Harmonix
Free - VanDerLee
With the Harmonix PhotoShop plug-in you can create complex waveforms. The waveforms generated by Harmonix are created by mixing (or superimposing for the more technically-minded) harmonic frequencies. All features of the waveforms are automatically scaled to fit the image (or selection of course) so you will not have to reconfigure an entire wave should you decide to change the image size.
