Loading a customised package on my computer I can use all of its functions easily. But I am looking to find the maple code of the procedure that make this function works, I am sure there is a trick but I am struggling to find it. I researched online quite a bit without any success as the threads I found about making your own packages are too technical for me.
Would anyone know how to do that?

Thanks in advance.

I can't solve probably very easy problem. How to plot a filled semicircle which is rotated across one axis by an angle alpha? I came to the solution which I don't consider as the best one (since e.g. it will not work for alpha=Pi/2*(odd integer)) and I believe someone of you will show me a better approach. Thank you in advance.

My solution:

alpha := (1/6)*Pi:
plot3d([x, y, y*tan(alpha)], x = -1 .. 1, y = 0 .. sqrt(1-x^2)*cos(alpha), axes = normal, labels = ["x", "y", "z"...

I made a prodecure:

with(numtheory);
divs:=proc(k)
local n,q:
for n from 1 to infinity do
q:=tau(n);
if k=q then break;
end if;
end do;
return [q,n];
end proc;
[seq(divs(i),i=1..20)];

I have make it for i from 1 to 100 too, but it should work in five minutes. I think it should be made somehow with the integer factorization, but i can't realize it. Can someone help me?

hi,

is there a procedure to convert a number (or list of numbers) into its english equivalent?

eg

 1 = "one", 2= "two", ......, 100 = "one hundred"

Preben Alsholm now i take another dynamical system , i found 2 critical points , which one is saddle and other one has too involved eigenvalues , but didn't know how to plot the digrams you did in the worksheet ! i dont know how to define seq() .

Thanks in advance

Hello again Maple forums, it's been a while but I'm confident I came to the right place :)

I'm trying to fit our data (attached: maphelp.mw) to this function of Z:

It has the linear parameters a-f...

Hello,

First of all I'm French so excuse my English.

I have some questions about Maple 14 on MacOSX,

1- I want to use the "proc()" fuction with an "if" fuction in the "proc()" but it's not workink, I tested many display with the "print" command to evaluate where is the problem and now I can say that the problem is in the "if" fuction. Here his my worksheet :

> suite := proc (n) local u, k, i; u := n; k := 0; for i from 0 to 10 do print(irem(u, 2...

Can somebody, please, try this command in Maple 16 (or at best Maple 16.02)?

Student[Calculus1][FunctionChart](x*exp(1/x));

In Maple 15 I get the graph in about 1s, however in Maple 16.02 it loads about 20s and it is even not as perfect as is in Maple 15. Furthermore, when I try to evaluate

st:=time():
Student[Calculus1][FunctionChart](x*exp(1/x));
time();

it says that it lasted only 1-2s. There is some problem...

Assumption:f(x)=x^2+2x

how to solve f(x+1) according the assumption.

this question is going to be asked has been done several times by me but no answere is sent,but i do it again:

f(x)=sqrt(x+1)→domain(f):[1,+∞),range(f);[0,+∞)

how to solve them at the maple15

Hi, i'm trying to solve the following PDE in Maple:

>

I have modeled something like a rope attached to a fixed frame at both ends. Is there a way to detach one end of the rope from the fixed frame during a simulation? Is there a better way to go about this? I want to be able to release one end of the rope during the simulation.

Any advice or thoughts will help.

Thanks 

There was mention to have simplify=false in Maple to stop it from it's automatic manipulation which would otherwise be considered obvious but not necessarily wanted. 

The idea brings up numeric manipulation. 

For example how do I force maple to factor out (1/3) from this :

a:= (1/3)*x^2 + (1/6)*x - (1/12)

to to show this

(1/3) * ( x^2 + x/2 - 1/4 )

Things brings up another question, the collect command...

Hi!

i have a short question. It should be easy to answer.

I use unapply which works fine but it seems as it doesn't save the result. If i call  Phi := unapply(A1[1], x1, x2); this gives me: (x1, x2) -> 1 - x1 -  x2 (the function I expected)

but when i call "Phi" it just gives me the symbol for Phi and not the function. Maple uses the symbol for following calculations.

Hi, while working on a worksheet a message abou kernel lost appear, saying to restart maple. I saved my worksheet (maybe I should  have not) and I restard it, but now my worksheet its a complete nonsense and I seem to have lost weeks and weeks of work. Is there anyway to recover my orginal woeksheet (the .bak file is also crushed) ?

Here is the crashed worksheet

thanks in advance
