Hi all,I am wondering if it is possible to change the real=True|False property of the symbols used by sympify/S created when parsing an expression.
E.g., S('sqrt(x^2)'), how can I then specify that x is real? While I can access the Symbol's using .atoms(Symbol) I can not work out how to modify their properties.
What is the best way of going about this? Regards, Freddie.
