DPGraph figures.

This figure shows the orbit of a hypothetical comet around the sun.
The orbit is an ellipse with eccentricity 1/2. The period
of the orbit is 12 years, and the dots show the position
at each year. The velocity vector is blue and the acceleration
vector is green.

10.3.

The following graph shows the space curve described by the vector
function **r**(t) = < cos(t), sin(t), 1 >.
The position vector of the moving point is blue in the
movie.

The following graph shows the space curve described by the vector
function **r**(t) = < cos(t), sin(t), sin(3t) >.
Here the moving point is shown as a box, and the position vector from
the origin is not shown.

The following graph shows the helix described by the vector
function **r**(t) = < cos(t), sin(t), t/(2 pi) >.
