Today we started class talking about how you need to be good at 30, 60, 90 and 45,45,90 triangles as well as being able to think even when things are not intuitive. (see first page of notes, shortest path is unexpected.)
We learned that a coordinate on a polar graph is labeled (distance, angle). Points on polar graphs have an infinite number of names. We also learned the formulas to convert polar points to rectangles points and vice versa. (this is all on the second page)
Plus we did a few examples. (see 3rd page)
