Glad to know, you got the answer all by yourself. Cheers. Keep it up.

@Joe Riel 

Thank you very much for the perusal of this long codes and constructive  useful comment. Cheers. Ramki..

Dear members,

With a little more search for the mistakes, I found out that the variable y was preventing  the plot from occuring. I changed it to y1 and the doc works fine. However  I request suggestions for any suggestions on improving the code for getting a simple and easy to read module.

Thanks for helping me.

Cheers.

Ramki

I have now learnt the meaning of parse more clearly.

I also found out using the suggested command 

SetProperty("MathContainer0","expression",parse(GetProperty("TextArea0","value")));

using  " parse(GetProperty("TComboBox0","value")) gets the pop up in MathContainer rather quickly.

Thank you very much.

@Thomas Richard 

Thank you very much. It works. Though both value and "value" works, I prefer now to use "value" as there must be some reason behind its rule.

Thanks to both acer and Thomas Richard for instant support.

Ramki.

@tomleslie 

I have understood, what expression means inside the container. Thank you very much for making it function.

Ramki

@Joe Riel 

Thank you very much for the input to my doubts. These are certainly useful in my present preparation of code for use in visualisation of functions and transformations. Thanks again.

@acer 

Radiobuttons, I will use for different function selections. Thanks.

@acer 

Thanks. I want the update of expression whenever there is a change in the expression.

Since the code is already in the ChangeE() procedure, to avoid duplication of command, I have replaced  the second code with calling the procedure, ChangeE() and it also works well.

 UpdatePlot := proc()

....
              ChangeE(); # This works as well.
    #     DT:-SetProperty("MathContainer0", ':-expression', q);
    end proc;

@acer

No sir. I have posted. I have not attached this document as you already have now. The command that works here does not work elsewhere. That document I have posted with question

  

@acer 

Thank you very much.

I shall try it out and find string or variable, which one is best. In the present document, it may be little difficult. I shall in any way find out the effect. Thank you very much. It seems the commands are very sensitive at times and i face this problem in mathcontainer. I am sending the same as another question next time.

Thank you very much again.

@acer

Thank you very much. It is very useful to know about the 'refresh' functionality. String identity for components is certainly more straight forward and clear to understand. cheers.

@Kitonum 

Great. Your idea of using Explore command for this case is the best. However, if I have to have additional commands for additional components involved in the programme, maybe, I say maybe, embedded components with module application would be better. I have to test it. I am sure if Explore command serves the same purpose, a great many complications will be avoided.

Thank you for the nice new command, I have learnt to use from you.

Cheers.

Format , Style, Style Management  and now if I select heading the paragraph style comes and I can do apace adjustments.

If i select any item under P, then paragraph style comes.

If I select any item under C, then character style come in which line specing etc do not come.

 I have now understood the arrangement and it is useful for me to learn now.

Cheers. Thanks. Ramki

@hhdizband 

I think it should be differentiate with respect to x and not y'.

If it is wrt y', then it is a very simple problem by putting x = y'. The problem becomes d [√(1+x^2)] / dx. Maple easily solves it.

For d() /dx, answer already sent by maple prime member Mr.Acer. It solves our problem. 

Cheers.
