ln cos exp x^y^z (^ as well as functional evaluations are right to left) cos x^2 = cos (x^2) (exponentiation done first) cos^2 x = (cos x)^2 (order of arguments is changed) cos^(-1) x = arccos x (^2 and ^(-1) mean completely different things) 1--1 = 2 (unary minus is done first) John ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
