What's the function of a function variable's function?
Interestingly, I found nothing in the user guide regarding this usage of a function variable:
CAS enter: r(t):=[tsin(t) 1cos(t)] Produces: r:=(t)>BEGIN [tsin(t),1cos(t)]; END; (t)>BEGIN [tsin(t),1cos(t)]; END; Example: A revolving cycloid at t=0 (rest), position r(0) => [0,0] rotates to pi radians, r(π) => [π,2], completes a full cycle at r(2*π) => [2*π,0]. Is there any further information on this? Dale
