- Click Line button and specify 2.0 point width for the function curve.
- Enter the following values:
- Y(t) = sin(t*4)*exp(-t/8)
- T From = 0
- T To = 6*pi
- T Step = (To-From)/200
- Put a checkmark into Same T for All Plots checkbox.
- Click New button to add another plot to the project.
-
Change its name to Envelope1 by entering the new name in the Name field.
- Change the line style to Blue, Dashed, 0.5 pt.
-
Enter the following formula in the Y(t) field: exp(-t/8)
-
Click the New button again to duplicate the last function.
- Change Y(t) field of the new plot to -exp(-t/8).
