I am trying to make an animation based on two sliders. They have to move synchronously. First, alpha_1 slider stays at 0, then alpha_2 moves from 0 to pi. Afterwards, alpha_1 moves by p/12 and alpha_2 follows, moving from 0 to 11pi/12 and so on and so on. Thus by tracing I want to show the resulting figure as shown in the geogebra file I linked. The problem is that the first slider starts too quickly and the has a set pace which does not let me animate the thing properly.
Does anybody know how to solve this?
