Maple is to me difficult. The first version I bought was Maple9, and it was more than 15 years ago. But, I couldn't use it, feeling it too difficult. But, three years ago, I thought Maple might be helpful to my study, and since then, I have continued to learn Maple. As I got able to read the Maple help, I think that I could get to use maple better now than before. But, I feel that I am a beginner yet.

Thank you for your answer.
In the end, I wrote a procedure.

a:=(-2*theta+1)*phi/(phi-1)+theta;
#making of minus_one
minus_one:=
    proc(a)
        simplify((-1)*numer(a))/(simplify((-1)*denom(a)));
    end proc;
minus_one(a); 

Happy New Year,

Thank you for the kindness of people who answered to my question here last year.
And, though I think I will ask questions seemingly trivial to you, I wish you will answer to
them as well. I hope this year will be a good year to you.

Take care.
 

I am reading that book now. Though written as intended as an introductory book, I feel it
difficult to read at some places.
And, I think that it is well written as readable like a nobel,  written as some stories for some themes in each chapters.

Thank you for showing your code.
I typed your code, then the figure I obtained was this.

Untitled2.pdf

As I don't think that this figure is terrible, I think that your problem does not occur in
my environment of macosx, El Capitan, and maple 2016.

Best wishes.

You can use printlevel as

printlevel:=3;

kernelopts('printlevel'=3);

 

@torabi 

Thank you for your reply. I don't know why, but the error message contunues to appear in my environment.

@vv 

Thank you for your comment.
Best wishes.
 

@Kitonum 

Thank you for your teaching.
But, I had thought that I had deleted my post of the title of "I have a question," and I posted another question in

http://www.mapleprimes.com/questions/220252-Booleanvalued-Procedure

So, I have posted the same question twice.
It's my mistake.

Thank you.

 

@vv 
Thank you for your teaching that it is not in Boolean context.

Both of
remove(t->t="a",{"a","b","c"});
and
remove(t->evalb(t="a"),{"a","b","c"});
bring the same answer {"b", "c"}, don't they.
As the first argument of remove is a Boolean-valued procedure,
the way of using t->t="a" rather than t->evalb(t="a") looks non-standard to me.

Thank you.

 

@Kitonum 
I have a question.
t->t="." in remove(t->t=".", b); is a boolian -valued procedure.

But, then, why does (t->t=".")(9); not return false like (t->t^2)(3); returns 9?
How can I have maple return false?

Best wishes.

Hello torabi,

I downloaded and executed your  printf.mw .Then, the following error message
appears:

Warning, computation is being performed near the boundary of the current precision, suggest increasing Digits to approximately 2001 or efficiency may be degraded
proc(x_bvp)  ...  end;

 

I haven't experienced that sort of trouble.
But, from your writing that you loaded your maple to not-yours PC,
I thought that another account is needed and it is verified by a computer
of maplesoft. But, I don't know such sort of trouble occurrs in the case of not 
having an appropriate account.

As another possibility I can pick up, your maple might not reading "standard library," from some reason such as you having changed its location.

Anyway, I think you need to contact with maplesoft.

 

@vv 
I'm sorry, but as I thought the design of your figure is very nice, and I couldn't draw it through right-click after plot3d(x^2...., so I thought I would ask you how you drew your figure. If you don't mind, I will be very glad if you tell it to me.

Best wishes.


 

@tomleslie 
Thank you for giving me examples of applying freeze and thaw 
to the question I posted. Surely, it helps to use them.
And, as I was unassure of using them yet, I couldn't remind of using them
myself. Thank you very much.


 

Choose Save as PDF, and open it with Acrobat reader.
Characters are dirty with Skim and Preview as for viewing
a pdf file made with maple if you choose "save as a pdf", so I think there might be some problem in creating a pdf file with maple, but in this case also, there is a rescue. On the time you print a maple file, you can do it  to ps, that is postscript format, file. And, if you open that ps file with
Skim or Preview, it transforms ps to pdf, and then you have only to save
it in the format of pdf.
