It's funny how Maple automatically evaluates an expression, it can be frustrating at times, but suppose the user wants it entered the way he types.
- sin ( 4 + Phi) #automatically evaluates the negative outside
- sin (-x -y -z + Phi)
Even though both expressions are the same it seems Maple prefers -sin to +sin, in the second example above Maple has now 3 extra negatives.
Is all we need just a double set of single quotes around our expression so that when we recall that variable it returns exactly how we entered it in?
b:= ' sin(x+y+z-Phi) '
sin( x + y + z - Phi)
Would that work? Where would that fail? Is there a better way?
