@Preben Alsholm It is very interesting, I never thought of it just because I never had any difficulties with this. I know that a lot depends on syntaxis, but my Maple always understands me in a right way.

I print:

K:=sin²(a+b)-sin²(a-b) 

and in the output i get:

K:=sin(a+b)²-sin(a-b)²

Maybe the matter is in the superscript? but it is automatic...

Anyway, I attach a little illustration for you, where the red script is for Maple Input and the black script is for 2D Input.

Sorry for endless silly questions, I just whant to understands the way it works)

Of course I will update to Maple 17 in the near future, but there are some reasons to finish this work in my current version. I use Mapple 13 be the way:)

Replacing I to J actually helps, but are you sure there is no other way to make it work? I work with physical formula so I wouldn't like to change designation of the physical quantities. 

Plus I used letter I with subscript (I_tr, I_ex,I₊,I_-), does it change anything?

And also in my work I use 'epsilon' and 'delta' instead of r and d respectively, just in case:).

@Markiyan Hirnyk Unfortunately, this code does not work for me too

Yes, I used this syntax, what's problem with that? Coud it be cause of my failure?
