Polar Graphing Concepts and Curves

Tony Hawk introduces graphing polar equations, focusing on R = S(theta) and R = cosine(theta). He explains how to graph circles, limacons, roses, and figure eights using sine and cosine functions. The video includes instructions for using graphing calculators to visualize these graphs. Key concepts include understanding polar coordinates, graphing techniques, and recognizing different polar curves.

What is the first step in graphing a polar equation like R = S(theta)?

• Find the derivative

• Draw a Cartesian plane

• Calculate cosine values

• Set up a T-chart

When calculating sine values for angles, what mode should your calculator be in?

• Scientific

• Degrees

• Graphing

• Radians

What shape does the graph of R = S(theta) form?

• Circle

• Parabola
