Maple #8 is due Thursday 16 Nov 2000 

For FULL credit STAPLE your sheets together.

Each plot must be rotated to a "nice" position and "look good (smooth)".
Each plot must have include axes and the title must include your name
and what was plotted. Note that the expressions below are not
necessarily in a form that Maple likes.

1&2 Plot the following spacecurves (from test 1 fall 96)
  1a. <cos t, sin t, cos 4t>
  1b. <cos 4t, sin 4t, 4t>
  2a. <t cos t, t sin t, t>
  2b. <4t, sin 4t, cos 4t>
3&4 Plot the following vector fields (from test 3 fall 96)
  3a. <y, x>
  3b. <-y, x>
  4a. <x^2, -y>
  4b. <-x, -y>
5. The curve <cos 3t, sin 5t, cos 7t>, 0 <= t <= 2pi is particular hard
to figure out from a spacecurve. One can use "tubeplot" with a "nice"
radius and get a better picture of the curve. Do so. (careful, tubeplot
can be very slow, decrease the radius and increase the numpoints.)
