Use the left and right arrow keys to adjust the angle, or use the slider to change it. It's not the most exciting project, but the neat part is that trigonometry is not used at all (not even the direction blocks). Check the scripts to see for yourself!
I basically just turned the Maclaurin series for cosine and sine into a parametric equation. Now, the coordinates can be calculated as a polynomial instead of a trigonometric equation.
