@Markiyan Hirnyk Most good art is created for art's sake.

To prevent cut-and-pasted sections of code and Maple 2D output from looking weird, select "Preformatted" from the pull-down list in MaplePrimes while your cursor is at the place where you want to paste.

@Alex Joannou Yes, it should work with any structure, even those as yet undefined.

@conn96 Well, I don't see the image either. Putting it in your avatar makes it too small to read. Put the image in the body of your message.

@J Rod I agree with you: It's an absurd change.

@conn96 Please type your question here, and do not use images.

The result in Maple 16 is

I see the significant difference. In M17, the first coordinate becomes the parameter. I agree that the M16 way is better.

Your statement in quotes is ungrammatical in mathematical English. I don't often criticize grammar, but in this case there are many different interpretations possible depending on how quantifiers are placed in the statement. Quantifiers are phrases such as "for all", "for every", "there exists", "there is", etc.

One possible interpretation is "I want to find conditions on a, b, c, d such that whenever A, B, C are three points with integer coordinates on the curve y = (a*x+b)/(c*x+d), then the centroid of ABC also has integer coordinates and is also on the curve".

Another is "I want to find constants a, b, c, d such that there exists a triangle ABC with centroid O such that all four points have integer coordinates and all are on the curve y = (a*x+b)/(c*x+d)".

And there are many others. Perhaps you'd be better off expressing the statement in symbols.

Would you please provide the exact sequence of commands, or an example of a sequence of commands, that behaves differently?

You can reduce the number of significant digits displayed for individual results by using evalf[n](...) where n is the number of digits desired. For example,

evalf(Pi);
                        3.14159265358979
evalf[5](%);
                             3.1416
