Intro to Calculus (Class 75)
Lesson Title
Polar Graphing (1)
Overview
The opener for today, Rocket Problem, focuses on deepening student’s understanding of a derivative at a point and the definite integral. The lesson takes a step away from our progression through calculus to work with a different coordinate system.

Key Attitudes
Math is about using what you know to create something new.
Key Ideas
Polar graphs are a different coordinate system.
The coordinates of a polar graph are the radius and the angle of rotation. The angle of rotation is considered the independent variable and the radius is considered the dependent variable.
Key Skills
I can plot points on a polar graph.
I can write an equation for a polar graph.
