 Author Comment/Response Gernot Wagner 07/21/04 6:42pm I am trying to check whether a function is positive, given that some of its variables fulfill certain inequalities. For example, is 5 * x + 2 > 0, given that x > 0? "Positive[5x + 2]" seems to be the function that does this, but I haven't found a way to input the assumption "x>0." "x = 3; Positive[2 + 5 x]" returns "true"; but "x > 0; Positive[2 + 5 x]" only returns "Positive[2 + 5 x]." I would greatly appreciate any help with this! Thanks, Gernot URL: ,
