Mike, Functions in Mathematica put there arguments in square brackets, not round brackets. Each type of bracket in Mathematica has a specific meaning. Then, you have to use f[x] and not just f in the Plot statement. f[x_] := 1 - Cos[E^(3x/4)] {a, b} = {-1, 1.5}; Plot[f[x], {x, a, b}]; David Park djmp at earthlink.net http://home.earthlink.net/~djmp/ > From: Mike O'Leary [mailto:Gremmie at cinci.rr.com] To: mathgroup at smc.vnet.net > > > I'm trying to plot this function > > f[x_] := 1 - (Cos(\[ExponentialE]^(3x/4))) > {a, b} = {-1, 1.5} > Plot[f, {x, a, b}] > > and I keep getting an error that says f is not a machine-size > real number at > x = -1.
