We are still on schedule for polar graphs. That means that Monday we discovered in class how to name and plot points and how to change point forms from polar to rectangular and vice versa. Download Polar Coordinate System Introduction Tuesday, we looked at graphs of polar equations and how to change equations from polar to rectangular and vice versa. Wednesday, students investigated some classic polar curves - the limacon (and the cardioid), the lemniskate, circles and roses. Today we learned how to write certain conic sections in polar form. Tomorrow students have a quiz on all the polar information they have learned so far and the assignment after the quiz is a "Polar Graphing" Download Polar Geometry investigation that focusses on how changing the values of theta affects polar curves. This and their parametric egg Download Parametric Project are the only assignments for the break - and the egg isn't due until Thursday, April 12, 2012. (The polar designs look so pretty on the eggs!) Enjoy the break!
