Hello all, I've got a really simple question... does anyone out there know how to define a bounded variable in mathematica? For example, I've got this function for which I am trying to determine if the derivative is positive, and two of the variables in the function are probablities and thus bounded between 0 and 1. Because I haven't bounded the probability variables, the derivative is positive under some conditions and negative under some conditions. Is there any way I can tell mathematica that these variables can only be between 0 and 1? Please reply to sbw at rice.edu Thanks, Scott
