Lesson Objective

Students will be able to graph parametric equations, convert parametric equations to Cartesian equations, and recognize the resulting graph from the combination of two parametric curves.

- How are parametric equations different from Cartesian equations?
- What is the drawback of converting a set of parametric equations to one Cartesian equation?

- parametric equations
- parametric curve
- initial point, terminal point
- cycloid

(graphing curves defined parametrically)

- Graphing and converting parametric equations
- DOK Levels 1-4

- calculating and analyzing projectile motion and circular motion
- determine the exact motion of robotic arms for welding, painting, or assembly
- describe the movement of satellites or celestial bodies
- reconstruction of 3D images from 2D data in MRI and CT scans

Considering a point on the curve as x and y values both being in terms of a third parameter, t, is new to students.
