I did two polar plots as you see and wanted to color the region between them.

> with(plots);
> a1 := polarplot(1, t = 0 .. 6*Pi*(1/3), thickness = 2, filled = true, color = black);
> a2 := polarplot(2*cos(t), t = 0 .. 6*Pi*(1/3), thickness = 2);
> a3 := polarplot(2*cos(t), t = -(1/3)*Pi .. (1/3)*Pi, filled = true, thickness = 2);
> display(a1, a2, a3);

The program makes the region colored red but there is an overlapping part which...

Can you help me how to program about the interference of wave on the water surface in Maple ?

Hi, 

I've bought NAG C Library for my mac in order to use it in Maple.

However, it seems that Maple doesn't know where to search for it.
Indeed, it returns

Error, (in NAG:-h03abc) external linking: error loading external library libnagc_nag.dylib: dlopen(libnagc_nag.dylib, 129): image not found 

I've installed NAG C Library in usr/Library

Thank you very much for your help 

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?

Let the points M_1(-2,3,-4), M_2(4,-1,3) and the two straight lines l_1: x=-t+3,y= 2t-4,z= t+2 , l_2: x=s+4, y= 2s, z= 2s-1 be given. How to find the shortest path from M_1 to M_2 of the form M_1 - A -B - M_2 or M_1 -C - E - M_2, where A belongs to l_1, B belongs to l_2, C belongs to l_2, and E belongs to l_1? In other words, what is the shortest path between M_1 and M_2 which intersects with l_1 and l_2? How to find it with Maple?

Hi there,

I would like to introduce my self and ask you for an advice. 

I have a four linked robot that i would really like to control by the meaning of the optimal control theory. The arm has 4 actuators (giving torques U) in corrispondence of 4 rotational joints. P parameters describe the system.

I got ht edynamic system with the Lagrangian method and now I have 4 2nd order...

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

So currently i am trying to programm a game. for that i would need a Textbox that is updating once the player makes an input. I have a textbox TB1 and a button with the action linked. the action that the button should make is calling an external procedure which in turn updates the textbox. But i currently i keep getting the following error expresion:

Error, (in Maplets:-Tools:-Set) invalid argument(s): [TB1]::string = [7, 8, 9]

So what die i do wrong.

Dear Maple experts

I want to find the co-efficient for z^k of G(t,z)=sum_i=1^infty a_i(t) z^i where z is a function of t.

How to write notation for logical induction programming in Maple like F# or Haskell having tuples?

such as 

Conj(A,Disj(B,C)) ...

I am trying to get Maple 16.02 to evaluate

cos(Pi/4 - I*ln(2))

using exactly the syntax I just typed.  The correct answer is 3/4 + I/4.  I cannot get Maple to give me this correct, simplified answer.  I have tried "expand", "simplify", and "value", and I get garbage containing terms such as

"sinh((1/2)*ln(2))".

How can I force Maple to give me the simplest answer?
