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 teaching me a good trick. Your way looks good.
I will use your way. Thank you.


seq(a[i],i=1..3) works as

a__1, a__2, a__3



works well.

In the environment maple18 and word mac 2008, the phenomenan of  the value of -1/3 Pi in your picture being cut did not appear.

The problem is rather the picture pasted onto word is darty like in the apendid file



I sometimes add my answers to old questions, though they are not spam or bulk.


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

#making of minus_one
    end proc;

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.


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





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


Thank you for your comment.
Best wishes.


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


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

Thank you.


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

Both of
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.


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
