# How do I plot purely symbolic functions?

Posted 11 years ago
 Hello,I need to plot the following function:x(t) = A * (wo*Sin(w*t) - w*Sin(wo*t))Is there a way to plot the function without substituting values for the constants?

 How do you imagine a purely symbolic plot to look?Not being able to grasp the concept of a purely symbolic plot, here is a Manipulate that explicitly substitute values: x[a_, wo_, w_, t_] := a (wo Sin[w t] - w Sin[wo t])  Manipulate[  Plot[   x[a, wo, w, t], {t, 0, 100},   PlotRange -> {Automatic, {-2, 2}}   ],  {{a, 1}, -1, 1},  {{wo, 1}, -1, 1}, {{w, .1}, -1, 1}]

 Thanks Simon, I didn't know that it was possible to write a loop like that.  I've seen my textbook's plots of functions who's amplitudes are made up of undefined constants; the textbook then shows a plot who's vertical axis' units are multiples of the undefined amplitude of the function.  So the first tic mark on the plot would read F/mw, the second tic would read 2F/mw, the third tic would read 3F/mw, etc.  The author of the book stated that the plots in the book were made using MathCad, so I'm not assuming Mathematica can do this also.  Thanks for the reply!
