Polar Area-Rathish Learning Targets - I can classify polar graphs by their shape - I can find the area of an inner loop (Limacon) of a polar curve Introducing Polar Area The formula for finding the area enclosed by the polar curve r between and is given by the formula: A = 1 2 α β r 2 Types of Polar Graphs: Graph of a Circle Equations: r a sin( ) r a cos( ) r a
Graph of a Limacon Equations: r a b cos( ) r a b sin( ) If b < a the graph of the Limacon has an inner loop If a < b < 2a the graph of the Limacon is dimpled If 2a less than or equal to b the graph is convex, and not a complete circle Graph of a Rose Curve Equations:

What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
