This is the thirteenth in a series of major topics in trigonometry, adapted from a series of lessons that I wrote for homeschoolers. it goes into great detail about what the system is and how it works. There are many examples and graphs to illustrate how to graph in this system. Websites are noted for more graphs. How to convert from polar form to rectangular form is discussed, but only for simpler situations. (For more complex equations, see your textbook problem section.) Extra polar form grids are provided. There are 2 to 3 lessons, depending on available time. Download the preview to see suggestions and complete content for this product.
