for me, it is a bug that should be corrected.  Thank you for the trick.

But I will have to make an important suggestion that in the contextual menu, I should have the choice between absolute or relative conversion.  Since the clickable facilities is a plus for Maple, I don't want to be obliged to use the long form of convert(43,temperature,degC,degF).  Quite unpracticle in a clickasble view.

But thank you acer for the clear explanation.

Regards,

@acer 

 

Than you very much for those codes.  Already, the first one was exactly it.

Thank you, thank you acer.

First one:

and the second one is:

@Carl Love 

 

The code I posted is actually the right one.  Of  course, the varible phi must be replace par t.  This is what I got:

when you look in front of it.  But when you look from a upper vieu, you get:

Wich is not a circle.

 

Is you plot in 3D is the sme?

 

@Preben Alsholm 

 

Yes, in P3, the upper limit is really L.  Sorry for that inconvenience.

That what happen when you cannot edit your post.

I have a function:

And I want to express it this way:

 

where

I express this function in a complex wave:

with

and

I want to calculate the probability of P(m=3), so I need to do

And that is the integral that Maple don't do:  But if you look carefull to the integrand, you have that

when muiltiply permit me to write it this way

and you get that


and  

If I made a theoritical mistake, pleas correct me.

 

Thank you in advance for your helpé

Thank you for this quick response Acer

@mehdi jafari 

 

You took the time to help me and I am very thankful to you.

@Carl Love 

 

I create a matrix M as you told me (55x1).  Now I did :

>Statistcs:-QuadraticMean(M)

And get exactly the average number of counts = 100484.309.  Witch is the answer given.  Then I did the:

>StandardDeviation(M)

and BINGO, I get the 1.2891675

Congratulation Carl!  You save my day.  Thank you very much. :-)

@Carl Love 

 

It is the first time I try that way and in fact, it did create a matrix.  Wow!

 

Thank again,

@mehdi jafari 

 

Can you tell me how you have made a link for your two files.  I don't see no icons that I can use to link a document in my question.  Thank you for your help.

OH!  I think that you use the green upward arrow.  I remember now.  :-)

@Carl Love 

 

But I have no idea how he arrive at that.  I will think about it.  Have you been able to make the worksheet that I have included to work?  More over, waht do you mean to «simply paste» the data in a Matrix?

But first thing first, thank you for you quick response.

You will find the data file «DataFrequence.txt» with the 55 numbers.  Then the file I have been trying to make work «FrequencyCount»

You will note that I added a last line to close the data file.

I the text that I read, it is said that the RMS deviation from the mean of thenumber of counts = 1.28 counts.

Maybe I can place the problem in the contexte.  It is a system that count the number of  maximum of a sin wave during 1 sec.  It use an electronic wave crest counter.  The goal is to introduce the uncertainty principle.

Oups, I have just realise that I cannot attach my two files.  So here is the code:

*************

>restart;
>FileTools[Text][Open]("DataFrequence.txt");

«Error, (in FileTools:-Text:-Open) permission denied»
# I have close the file before.
>for i to 55 do A[i] := FileTools[Text][ReadFloat]("DataFrequence\
  .txt")
  od;

>for i to 55 do A[i] od;
 
>stats[describe, quadraticmean]([seq](A[i], i = 1 .. numelems(A)))
>FileTools[Text][Close]("DataFrequence.txt");
%;
Error, (in FileTools:-Text:-Close) file DataFrequence.txt is not open

**********

 

and the data:

100484

If there is another way to proceed to give you acces to those files, don't hesitate to tell me how.
