As I recently acquired Maple Flow 2022 and have no experience with Maple ... but here is what I have found ...
This Works: convert(2 Unit(rad),degrees)=114.592*degrees*rad
No Workie: convert(2*Unit(degrees),units,radians=
No Workie: convert(2*Unit(degrees), radians)=
So, since Maple Flow2022 runs without the user owning Maple ...
I'm guessing not all Maple language/commands work in Maple Flow 2022
Or, I just don't know how to properly enter them in a Maple Flow 2022 Worksheet.
Regardless, I think Maple Flow 2022 is its own product and provides a nice front end GUI that will appeal to many new users.
And, all that said, I am still feeling my way along the learning curve so others are certainly more of an expert than I am at this stage.
