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?
