Cool video. Question - is there any way to reduce the amount of redundant calculations when plotting a curve like 'b'? I'm working on similar (but more complicated) parametric service which involves the unit normal vector of a curve. I have something similar to your curve 'b', and I'm finding that all the redundant calculations really slows Geogebra down, especially as functions get nested. For the life of me I can't find a way to get Geogebra to store a vector in the while drawing a curve or surface so it will use the current numerical vector instead of going back and recalculating the vector by function definitions. Any help? Thanks!

couldn't you've defined the curve b as a'(t)/d(t) ?
