When there is a third variable, a third parameter on which
and
depend, parametric equations can be used.
To graph parametric equations by plotting points, make a table with three columns labeled
and
Choose values for
in increasing order. Plot the last two columns for

When graphing a parametric curve by plotting points, note the associated
t -values and show arrows on the graph indicating the orientation of the curve. See
[link] and
[link] .
Parametric equations allow the direction or the orientation of the curve to be shown on the graph. Equations that are not functions can be graphed and used in many applications involving motion. See

Projectile motion depends on two parametric equations:
and
Initial velocity is symbolized as
represents the initial angle of the object when thrown, and
represents the height at which the object is propelled.

Evolution models refer to mathematical and computational representations of the processes involved in biological evolution. These models aim to simulate and understand how species change over time through mechanisms such as natural selection, genetic drift, and mutation. Evolutionary models can be u
