I'm really n00b in Mathematica, so please bear with me, as this seems to be my only option to learn how to do what I wany to do.
I have a system of two differential equations:
y' = v[t] v'[t] = -a^2y
Now, assuming I know the solution of this system is: $y = cos(a\,t),\ v = -a\,sin(a\,t)$, I want to plot the integral curve of the two, on the v-y surface, with
a t getting values from 0 to
I've tried various combinations of
VectorPlot and many other functions, without any success, although I think it's suppose to be really simple. I've tried also to make a plot in 3D with
VectorPlot3D, but to no avail.
I'll appreciate any help.
