I am trying to evaluate the signs of some symbolic expressions. The following is a simple example. Suppose: a > 0 b > 0 c > 0 0 < d < 1 We know that a*b*c - a*b*c*d >0 Can I define the variables in such a way that Mathematica can evaluate the expression. Thanks, Dan Rogers ==== [MESSAGE SEPARATOR] ====
