ZGrapher  ZGrapher 1.4
This program can graph y(x), x(y), polar, parametric and table-defined functions. Calculus features include obtaining derivatives, equations of tangents and normals, numerical integration, regression analysis. Graphs, coordinate plane axes, coordinate space may be fully customized. Your graphs may be exported to BMP, GIF and PCX pictures.

Harmonix 1.1
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.
