We can use parametric equations in three dimensions as well.

  1. We begin in two dimensions. Sketch the figure produced by  and . Describe the figure sketched on the interval .

  2. Now suppose we have , , and . Make a table with four columns: , , , and . Put in several values of to answer the question: what happens to the point as increases from to ?

    Imagine the -axis as coming out of the paper on your desk vertically.What would it look like if you plotted the points of a circle on a graph, but moved vertically out of your paper while doing so?

  3. How would the figure be different if the equations were , , and ?
