Errors in this video:

At about the 50 second mark, he states and labels the top of the unit circle as pi over 4, when it should actually be pi over 2. He also labels the point on the left as 4/4 when it should have been 4 pi over 4. At about the 2 minute mark, he says "6 over 6 pi" when he should have said "6 pi over 6".

Lesson Summary:

This lesson teaches how to find a point on the unit circle given a real number. The key is to break the number down into fractions and then use the unit circle to find the point. By understanding how to break down the numbers into fractions and using the unit circle, you can easily find any point on the circle.
