It would be nice if Maple had a procedure which could turn a procedurelist into a listprocedure.
I use these words in the sense they are used in dsolve/numeric.
Thus by a procedurelist I mean a procedure returning lists (of numbers).
By a listprocedure I mean a list of procedures all having the same formal parameters and each returning one number.
Thus a `convert/listprocedure`should accept a procedurelist p as input and give as output the corresponding listprocedure [p1,p2, ... pN] where N is the number of elements in the output from p.

I tried making a `convert/listprocedure` myself and in doing so found that it was not totally trivial.
I had lots of problems but did end up with something that seems to work.

But my main point is that Maple ought to have some such facility either as described available to the user or by changing fsolve, complexplot or what have you, so that procedurelists are accepted.

Hi all,

I seem to have triggered a nasty bug in Maple 17.  Consider the following code:

  BlahObject := module()
    option object;
    export BlahMethod := proc()
    local C, d, i;
      add(C[i]*d[i] + C[i], i=1..4);
    return NULL;
    end proc;
  end module;

It triggers a Maple kernel crash for me when doing object construction:

 B := Object(BlahObject);

The offending line is the one with add( ). It is ok if I add C[i]*d[i], but when the line contains both * and + it causes kernel death every time.  This is strange as the proc is not even being executed... only constructing the object. 

I am running Maple 17.02, it's also present in 17.01.  But interestingly, it runs fine in Maple 16.  Bug in Maple 17? 

Thanks,
Ian.

There seems to be patterns for sin(10^-k) for rational k;

Here we have the "floats."

n sin(10^(-n-1/2))

1 0.03161750640

2 0.003162272390

3 0.0003162277607

4 0.00003162277660

5 0.000003162277660

6 0.0000003162277660

7 0.00000003162277660

More later on using the mantissa. You're welcome to join me.

I define a partial repeating decimal as shown in the following example: if you have the decimal expansion 0.1728394877777777777777777777771939374652819101093837... 7 is called a partial repeating decimal.  

Back in 2000 I noticed a pattern in the decimal expansions of sin(10^-n) for growing n. Here is table of some integer n:

n                sin(10^-n)

1 9.98334166*10^-2

Back in 2000 I published A034948, A036663, and A036664 in Sloane's Integer Sequences, now OEIS.

But today I decided to find the exact values of some such quotients.

1/9801=0.repeating(000

I have a previous post on this, but the discussion completely missed the situation I was presenting.

The big problem is: The (vertical) writing cursor often does not move on the visible worksheet when a new location is clicked with the mouse or the arrow keys are used, and moving with the arrow keys often leaves a trail of writing cursors along the line between exisiting symbols. Luckily, Maple internally seems to know the correct (intended) location of the...

When I run "sum(a[1/k],k=1..n);", I get "Error, (in IntegerSub) too many levels of recursion". But it's OK to run "product(a[1/k],k=1..n);". Furthermore "Error, (in IntegerSub) too many levels of recursion" cannot be caught.

Today maple is being used as a helpful tool, but teachers should learn mathematics in depth, and in this way use the primitive concepts of mathematics. This very well use the algorithms that reduce the lines of code in the resolution of a problem, but it is very necessary to use command to demonstrate theorems, since inico to completion, and then be tested with new commands that meet on a line of estio the problem code. What do you think about the development of mathematical procedure, using native commands?

The list of the GUI problems is long, so I'll just summarize some of them.

In text groups, when the writing cursor is moved, the cursor is often not visible at the new position (where it actuall knows it is at), but often remains visible in a trail of places where it previously was.

In Help, the first letter of the search word is usually missing so that it is necessary to start with a space. Also in Help, both the scroll bar and the actual search...

My system: Windows 8 x64, Maple 17.01 x64.

After launching Maple we have a process maple.exe (C:\Program Files\Maple 17\jre\bin\maple.exe) that consumes approximately 80MB.

We run the following piece of code:

>restart;
>for i to 1000 do
>factorial(300);
>end do;

After running for the first time of this code the process maple.exe consumes 100.5MB
After second running of this code the process maple.exe consumes 111.6MB
third running --- 122.4MB

I am pretty new to programming in Maple and trying to learn the language. One thing I needed was how to handle lists in a specific way. I have used many hours on this issue now and even asked questions in the Questions section. Other users helped me with clever tricks and I am grateful for that. What is left is however a feeling that one need to know a lot of rather Ad Hoc commands to accomplish your tasks. I looked for operations in the ListTools package, going through all...

Let d be the Feigenbaum delta constant 4.66920160910299067185320382046620161..., a be the Feigenbaum alpha constant 2.50290787509589282228390287321821578... and m be the MRB constant 0.18785964246206712024851793405427323....

d*m - 2 (600 a - 2537)/(5 a - 2373) = 9.232940534412995...*10^-19

or you could write

1/10*(d*m + 564446/(2373 - 5 a)) - 24 = 9.232940534412995...*10^-20

I'm fairly sure I discovered a bug with the Maple 17 Calculus Integration tutor.

I was working on int((x^2+2*x)*cos(x), x);.

The first step that the tutor wants you to do is to rewrite the integral by factoring out an x from the first term, and changing cos(x) to -sin(x).

The next step is to rewrite it again, this time changing sin to cos, making the intergal  -x(x+2)cos(x)

Next, the tutor distributes the X again, making the integral -(x^2+2*x...
