A Functional Programming Question

Dear MathGroup, Suppose I have three equations. eqns = {a x == 0, b y == 0, c z == 0}; I want to divide out the constants a, b, and c. I can do it this way: eqns[[1]] = (#1/a & ) /@ eqns[[1]]; eqns[[2]] = (#1/b & ) /@ eqns[[2]]; eqns[[3]] = (#1/c & ) /@ eqns[[3]]; eqns {x == 0, y == 0, z == 0} Is there a simpler method for doing the calculation in one statement with functional programming, say using MapThread over eqns and {a,b,c}? Is there any other simple approach? David Park djmp at earthlink.net http://home.earthlink.net/~djmp/
