Interactive video lesson plan for: How to express the polar point multiple ways (KristaKingMath)

Activity overview:

► My Trigonometry course: https://www.kristakingmath.com/trigonometry-course

A single coordinate point in polar space can be expressed in an infinite number of ways. That's because part of the polar coordinate point is the angle theta.

Since theta represents the angle between the positive direction of the x-axis and the polar point, and since you can keep adding or subtracting 2pi radians to get back to the same point over and over again, there are an infinite number of ways to get to the same angle.

In addition, you can express r (the distance between the origin and the polar coordinate point) as a positive value, or as a negative value. If you express it as a negative value, then you'll need to be a rotation of pi radians around the origin from where the point actually is.

Hi, I’m Krista! I make math courses to keep you from banging your head against the wall. ;)

Math class was always so frustrating for me. I’d go to a class, spend hours on homework, and three days later have an “Ah-ha!” moment about how the problems worked that could have slashed my homework time in half. I’d think, “WHY didn’t my teacher just tell me this in the first place?!”

So I started tutoring to keep other people out of the same aggravating, time-sucking cycle. Since then, I’ve recorded tons of videos and written out cheat-sheet style notes and formula sheets to help every math student—from basic middle school classes to advanced college calculus—figure out what’s going on, understand the important concepts, and pass their classes, once and for all.
