Thank you for showing your code about animation.
Following what has been put before the present animation is being shown,
how for the animation to be seen surely changes is very natural.

But, I hadn't  think about it, before I see your present post.

Thank you. I noticed that the design is different between maple for windows and for mac.There isn't type of RTF. And as for html, I could not have the html file I created show expressions which is the outcomes of Maple. I haven't noticed it because latex(expression) works well.

@Axel Vogt 

Thank you for your reply.
I couldn't fined the way to export the part of expression to .rtf or .html.
Is it by from File in menubar->Export As->html?

So, I am writing thinking whether I could be taught it by you.

@John Fredsted 

Thank you. I noticed it. Thank you.

By the way
?worksheet,reference,hotmac (shortcut_keys)
shows the page of the shortcut, one of which are shown with

@John Fredsted

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

, ,

And,

seq(cat(a__,i),i=1..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.

@Kitonum 

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.

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.

@badzline 

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.
