Parametric Equations
In calculus, you worked with parametric equations where you would have
a three variable system, with t, x, and y. Both x and y were functions of
t, and so you picked different t values, and then plotted points based
on the resulting x and y variables.
Example:
Set x = 2t and y = 3t-1

The variable 'c' appears in both the function for the y-axis and the
x-axis. You will vary 'c' as you plot data points for the
Zimm plot. The Zimm plot will have several parametric plots (straight
lines), with each parametric line corresponding to a different scattering
angle, as shown below:
