Hi everyone, I am having problems when trying to plot an expression in a Dynamic model using manipulate tool. For example, in this simple code I can plot the function (first plot), I can evaluate its value in a manipulate environment (second plot), but when trying to plot in a dynamic environment I just get empty axis (third plot). myfun = x^2 + 3 t x ; t = 1; Plot[myfun, {x, 0, 2}] Clear[t] Manipulate[Evaluate[myfun], {x, 1, 2}, {{t, 1}, 0, 10}] Manipulate[Plot[Evaluate[myfun], {x, 1, 2}], {{t, 1}, 0, 10}] Any idea of what I am doing wrong? I will really appreciate any guidance. Regards, Marcel Goic
