Toolbox of Elementary Functions

thingiverse

This is a set of Elementary functions modeled parametrically in OpenSCAD. The modeling process was inspired by mathgrrl's parametric knots, but I used a cylinder in two dimensions instead of her sphere in 3D. **Intended usage:** * Introduce the idea of a toolbox of functions to students. * Demonstrate rigid translations and reflections by physically moving plastic models. * Add a tactile element to lessons for better understanding. Some curves have small L-shapes attached, marking one unit on positive x and y axes. These L-arms help orient curves so it's easier to start in the same place. Files are provided in three formats: * big.stl - sized for 200x200mm build plates, suitable for teachers in front of 20-30 person classrooms. * small.stl - scaled down so one unit equals one cm, ideal for students using multiple copies at their desks. A piece of 1 grid/cm graph paper may be useful (also attached). * .scad - source files that can be customized for scale, line width, and desired range. Creating new functions is a matter of putting the desired parametric equations into the function f(t) definition.
