# Animation of a surface over time

I have a function $f(x,y,t)$ that depends on the spatial variables "x" and "y" and the temporal variable "t". how can I do an animation in mathematica that shows the movement of the surface over time? in what formats this animation can be saved? Can you give me an example?

• Can you give an example f[x, y, t] that you want to animate? – J. M. is away Sep 8 '17 at 4:01
• Yes, for example: f[x, y, t] = (Exp[x + t] - Exp[x - t]) Cos[y] – Julio Abraham Mendoza Fierro Sep 8 '17 at 4:23
• Perhaps it is also worth checking out the description for the Animate function – Dunlop Sep 8 '17 at 4:26

f[x_, y_, t_] = (Exp[x + t] - Exp[x - t]) Cos[y]
