### I'm having trouble plotting the velocity and acceleration vectors of the following space curve (r3). May anyone help guide me in the right direction to solve this problem?

var('t') r3(t) = (cos(t/2), sin(t), t/6) v3 = diff(r3(t),t) a3 = diff(v3,t) curve3 = parametric_plot3d(r3(t),(t,0,4pi),thickness=0.5) velvecs = Graphics() accvecs = Graphics() for k in range(9): velvecs += arrow(r3(kpi/2),r3(kpi/2)+v3(kpi/2),color='red') #Line 26 accvecs += arrow(r3(kpi/2),r3(kpi/2)+a3(k*pi/2),color='blue') show(velvecs+accvecs+curve3,axes=False)
