I often encounter output of the form Out[1]= Sqrt[a^2] , where I know a is real and positive, and therefore would like to see Out[1]= a . How do I get Mathematica to assume that all quantities are real? Real and positive? Can this be done globally, for an entire session? Thanks in advance. ----------------------------------------------------------------------------------------- Rob Lopez Department of Physics University of Chicago ----------------------------------------------------------------------------------------- ==== [MESSAGE SEPARATOR] ====
