Creating parametric functions
An example of a parametric function is shown below:
x=t2, y=t–3
To enter parametric equations into the Newton Works graphing calculator, you can
use the following format:
x(t)=f(t)
y(t)=g(t)
p(t)=[x(t),y(t)]
or
p(t)=[f(t),g(t)]
For example, using the above parametric equation, you can enter:
x(t)=t^2
y(t)=t–3
p(t)=[x(t),y(t)]
or
p(t)=[t^2,t–3]
You can graph parametric functions or view the results in tabular format, just like any
other function.
