a[x_, t_] = Sin[34*x - 2*t]; Animate[Plot[a[x, t], {x, 0, 2*Pi}], {t, 0, 5}] Bob Hanlon ---- Rui <rui.rojo at gmail.com> wrote: ============= I'm new in Mathematica. I have version 6.0.3.0. I'm trying to create an animation or a plot, something simple. I found Animate[]. I can make it work fine by doing something "like" Animate[Plot[Sin[34*x-2*t], {x, 0, 2*pi}], {t, 0, 5} ] But if i have my expression stored in a variable i can't... a = Sin[34*x-2*t]; Animate[Plot[a, {x, 0, 2*pi}], {t, 0, 5} ] leaves the animation blank. I tries all variants I could think of and I always fail. I actually wanted to create several animations of expressions i have stored in a list, and I could do it one by one manually but I wanted to learn the proper way and I'm frustrated already. Any ideas? -- Bob Hanlon
