I am evaluating some complex expressions with mma, and I want to be
able to declare a variable as being real. I can do so for a single 
expression with Complex Expand having no second argument, but I want to be able
to declare a variable as real for my entire notebook,so commands like
Real and ComplexToTrig don't consider an imaginary part to my variables.  Is
this possible?  Thanks.
