@epostma 

I did a cut-and-paste of the edited block of code in your latest post, and unwrap_trig_functions now runs just fine on Maple 2017.3

Thank you so very much for coming up with the code to accomplish this functionality, Erik.

@gkokovidis Thanks for your reply, Georgios.

I copied and pasted the .mw file you attached to your last post. The first few lines execute OK. When I execute the code block for unwrap_trig_functions, I get the error message: reserved word "if" unexpected.

I'm using Maple 2017.3 on Windows 10.

When this code is executed, as posted, Maple displays an error message that the reserved word "if" is unexpected. How can this code be edited so that it is accepted by Maple?
