Hello, I have a function like: phi(a,t) = sin(2*pi*(t-a)/T' + a/T) where "T" is itself a function of "a" like here: #### Plot3D[Sin[2*\[Pi]*((t - a)/3 + a/(a + 1))], {t, 0, 9}, {a, 0, 9}, AxesLabel -> {"t", "a", "ex"}, Lighting -> False, ViewPoint -> {0, 0, 100}, PlotPoints -> 40, Mesh -> False]; #### Therefore, I would like to define T separately. Something like here: #### T[a_] = a + 1; phi[a_, t_] = Sin[2*\[Pi]*((t - a)/3 + a/T[a])]; Plot3D[phi[a, t], {t, 0, 720}, {a, 0, 720}, AxesLabel -> {"t", "a", "ex"}, Lighting -> False, ViewPoint -> {0, 0, 100}, PlotPoints -> 40, Mesh -> False] #### But as you can see, both plots do not look like the same. How can I define a "T" as a function of a separately? Thank you in advance. Aitor
