sinusoidal graphs

[Andrew Taylor-3]

I am trying to graph an electrical sine wave based on the general expression

"y=A sin(Theta). Without values, I just get a straight line. I tried using the

complex form [for instantaneous voltage value- v=V(sub P)sin(2pi*f*t)-V(sub P)

is peak voltage], but I either don't know the proper syntax. or don't understand

the math well enough.

When I enter values for the variables, the program will not recognize the units.

How do I graph a sine wave w/ actual curves, instead of a flat line?

1. Do your axes use radians (and not degrees)?
Check by going here:  Edit -> Axes -> Settings -> Trigonometry

2. Remember to use x as the variable and not t or Theta.

3. Please provide an example of a curve which you are trying to draw.
