Bezier curvatures as matrix operations and without a slider
Hi, I have two questions:
1. I completely fail to to figure out how to build a bezier curve in GeoGebra using matrix operations as shown here: http://pomax.github.io/bezi... . I do understand the operations presented on that website, but I don't understand how that could be made in GeoGebra. Is anybody perhaps aware of a worksheet that is self-explaining or able to explain this?
2. Right now when building a (cubic) bezier curve I use four points and this well known formula: (1 - t)³ P_0 + 3(1 - t)² t P_1 + 3 (1 - t) t² P_2 + t³ P_3 . To draw the curve, of course, I use a slider and the locus tool. But is it also possible to make the locus tool work with something like: t=Sequence[t, t, 0, 1, 0.01]? I mean a slider is okay, but even when I don't need it, I cannot hide the slider itself, because that also hides the whole locus/curve.
