Phase Plane

If two functions are returned by Solve ODE, then a phase plane can be plotted. The phase plane is the curve defined parametrically by the two functions.

    x = y
    y = - x
x(0) = 0
y(0) = 1
, Functions defined: x, y

  1. On the Plot Components page of the Plot Properties dialog, set the Domain Interval from -3.15 to 3.15.

  2. For the second view, on the Axes page of the Plot Properties dialog, check Equal Scaling on Each Axis.
