@Carl Love 

Thanks

Indeed i am struggling with the loops and try to improve this
Two forms of the do loop 
- for-from loop
- for -in loop

Your loopexample in the SumList procedure seems to be advanced ( don't know r+)
Tried making the factorial procedure, but make no progress yet.

Yes, the simpler loop example for the procedure SumList you mentioned, is for now easier to understand 
The capital S in the  do loop is a remainder that S is the last executed statement ?

Thanks 

I found them back the worksheets from Roger Kraft about programming in Maple

@dharr 

Thanks

Cannot be shorter :)

@Axel Vogt 

Thanks 

Thereis not much to find about this in the book until now  

@Pascal4QM 

Thanks

@Carl Love 

Thanks

The use of the until statement, why to apply in what code context is yet not clear for me

@Axel Vogt 

Thanks

Yes,but is now by using a procedure for a general case..for all N 

@acer 

Thanks

Interesting books for starting for programming and hopefully i can make some progress

It is not my goal to go very deep in the programming skills, because its probably not neccesary and difficult

@rlopez 

Thanks

Yes, i did, but decided to use the book short introduction for now.

@acer 

Thanks

Makes it not easier to learn some programming in Maple (only one edition from 2002) 

I think there is no other book what teaches a introduction in programming in Maple ?

Can't folllow your explanation what is all wrong with this procedure  

Must a variable be declared in a procedure to be local ?, if not they are global ? : assigned outside the scope of the procedure

Thanks

The book mathematical computing -An ntroduction to programming using Maple   is way back from 2002 ( don't think there is newer version ? ) 

When i execute the code nothing happens.

@acer 

Thanks 

Makes the graphs really looking good with the legenda! 
i did some adjustment to your code in order to follow the task in two parts
 (part1 :draw 5 deratives, part 2: draw f, f' and f'' and reasoning  geometric the 3 graphs)

Thanks

I chanced at start at options the Output display to Maple input,that's the culprit

its my own fault..forget that i did this

Well,it is solved now

exercise set 2-task2

So, the fo  rmula for the [i,j] element is i^j , as i goes from 1 to 3 and j goes from 1 to 4. (Realizing this is likely one of the purposes of the execise.)

But look at these:

Array(1..3,1..4,(i,j)->i^j);

               [1  1  1   1 ]
               [2  4  8   16]
               [3  9  27  81]

A := Array(1..2,1..4):
for i from 1 to 2 do
  for j from 1 to 4 do
    A[i,j] := i^j;
  end do;
end do:
A;

               [1  1  1  1 ]
               [2  4  8  16]

Array(1..2,1..4,(i,j)->i^j);

               [1  1  1  1 ]
               [2  4  8  16]
