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? If you're interested, here's the file: http://www.easy-share.co...012623/waveforms_test.smRegards, Vlad.

SMath Studio requires to use "x" as a variable of function to plot inside of the Plot region. Also, to avoid "Units don't match" error you should specify Unit of the function's argument. Here is the results:

Thank you, I meant to say that I tried u(x) but I didn't add units. Btw, Ctrl+Space doesn't work in graph and neither autocomplete, but Ctrl+U does; if it's meant to happen that way, don't mind this.
Regards,
Vlad.
