I do not have any code to produce yet.  I want to have Maple animate a bouncing ball on some 3d surface.

There are two normals to a point on a curve.  How do I get the PlotPositionVector of Student[VectorCalculus] to point in the other direction. 

with(Student[VectorCalculus]:

R1:=PositionVector([p,p^2],polar[r,t]):

PlotPositionVector(-R1,p=1..2,normal=true,points=[1.5])

 

The normal vector points towards the insided of the curve.  Can I use PlotPositionVector to have it point the opposite way (towards the outside of the curve)?

How do I know if I have the latest Maple build id?  What is it now?

If I have several sets of listed data of different lengths,

a1:=[1,2]
a2:=[5,3,4,5]
a3:=[4,8,4,5,3,2,3,4,5]
a4:=[2,2,5,4,7,8]
...

How do I join the 1st positions into one variable and the 2nd positions into another and so on?

How do I find all words beginning with "FL" and ending in "S" ?
