Regarding Maple 18 .. this is as far as you can go on a Windows XP machine with SP2.  One needs the service pack 3 to continue further with newer versions of Maple on a Windows XP machine. 

As for Maple 2019, interesting new features, although no support for MP3.  I believe of the Big M's Maple is the only one which does not support MP3.  Both Matlab and Mathematica support mp3 files.  

@acer good to know.  Thanks Acer.

Maple 12 to Maple 2016 is ok.  Maple 2017 on experiences this problem.

yeah, I did realize that. 

He could use the layout pallete for that, I think but it's still math format.  Otherwise the only way I do it in text is by toggling in and out of math formats using f5.  I don't think you can get out of just using a text format for subscripts and superscripts - you have to use the math format.  (and if you don't need Maple for the document just use Microsoft Word)

@digerdiga , it also doesn't work with anyone elses solution, but acer has the key :)

Yes I know he's still around.  I'm just hoping his valueable contributions weren't erased when (it appears) he removed his account.

In this case, would it be ideal if Maple just calculated to a few digits beyond the setting by the user?  Something like having internal guard digits.

This way calculations that come up would only have 1 digit possibly changing when more Digits are added rather than say 5 or so digits changing. 

Wether it's right or wrong or it is the way it is.  I'd rather see only one digit changing. 

It works in Maple 2018.  Since Carl Love was unable to duplicate your error, then it is most likely there is something wrong with your Maple version. 

@Konstantin@ Upload the worksheet and we can execute to see if the same error appears from your generated worksheet. 

Also try your code in worksheet mode and see if you get the same result. 

It's possible there are errors being generated in your worksheets.

Sorry, how was the y coordinate of the tangent circles found?

@tomleslie thanks for showing how to do it using the geometry package.

Turns out I needed to anchor some constraints in Geometry Expressions.  I am getting proper results now.  The output Geometry Expressions gives

@mmcdara thanks. 

I actually entered this into Geometry Expressions but it sometimes spit out some monstrous equation.  And depending on how I initially set everything up, it would just sit there calculating an output with no response. 

Thanks for the answers vv and tomleslie

Very interesting Samir.  Thanks for the insight Maple can give.

It would be interesting to see how one would start from scratch, take any book, and have Maple do everything from the start - find the characters and create the data.

An example epic novel would be the Malazan book of the Fallen which has over 700 characters.  The world of Malazan makes the Game of Thrones pale in comparison.
