This seemed a bit different than "Bode" thread earlier, so I opened a new one.
Suppose I have frequency given, I can calculate w=2*pi*f , I even have units. But if I want to go further and set up a signal, u(t):=U*sin(wt), I would need to define t as a variable. The only way I have seen this possible is by assigning t:=range(x,y,optional_z). This is fine until now, but if I want to plot u(t), it doesn't show a thing, but it calculates for some 6.2 sec. I thought it doesn't like units so I removed them, this time it calculates for about 5.5 sec, but still nothing. Am I doing something wrong or should I just wait?
