Hi guys. How do you plot a graph (parametric, in my case) and a graphic (arrow, as vector) in one "window" of manipulate? I'm trying to plot a clotoide with vector of velocity and acceleration... Here's what I've got so far: Manipulating the arrow by itself: Manipulate[ Graphics[{Red, Arrow[{{Part[First[R[t]], 1], Part[Last[R[t]], 1]}, {Part[First[R''[t]], 1], Part[Last[R''[t]], 1]}}]}], {t, 0, 5}] Manipulating the clotoide by itself (R[t] is the x and y's of the clotide): Manipulate[ ParametricPlot[R[t], {t, 0, t}, PlotRange -> {-3, 3}], {t, 0.001, 4}] How do I COMBINE those two?! Thanks in advande
