In a notebook (with typesetting enabled), whenever I apply simplify to a simbolic function, the result is expressed in terms of the identifier of the function, rather than its latex name.
For example,
var('x')
my_func = function('df',x,latex_name='\Delta f')
my_func
returns ?f(x)
but
my_func.simplify()
returns df(x)
Is there any retain the latex name throughout simplification?
