Trigonometry Assistant

This is a Trigonometry Assistant, it helps drawing sinuses, co-sinuses, tangents and co-tangents. This is for a scale where Y axis is 1cm (2 grids) = 1 and where X axis is 1.5 cm (3 grids) = 180 degrees (Pi/2), that is the standard scale for drawing trigonometry functions in math. It is a really fast, clean and nice looking way of drawing those functions. It takes around 2-3x less time to draw a sinus (and others) wave with this than by hand and its always turns out perfectly.
