Trigonometric ratios are used to find the unknown side or angle of a right-angled triangle. There are three different trigonometric ratios, \(\sin(\theta), \cos(\theta)\), and \(\tan (\theta)\). Each ...

It can be computed as 2/(sin(alpha))^2 where alpha is the pressure angle. By default, the gear modules produce corrected gears. You can override this by specifying the profile shift yourself. A small ...

This file provides functions and modules that construct shapes from a list of cross sections. In the case of skin() you specify each cross sectional shape yourself, and the number of points can vary.
