How to remember the points on the unit circle

The video tutorial explains how to identify and use special triangles, focusing on the 30, 45, and 60-degree angles. It covers the use of fractions with a denominator of 2 and demonstrates how to quickly rewrite these points using square roots. The tutorial also discusses the impact of quadrant positions on the signs of the values, providing a quick method to remember these concepts.

• 15, 30, and 45 degrees

What is the common denominator used when rewriting the points of special triangles?

• 3

• 1

• 4

• 2

How are the square roots arranged when rewriting the points of special triangles?

• sqrt 1, sqrt 3, sqrt 2

• sqrt 1, sqrt 2, sqrt 3

• sqrt 2, sqrt 3, sqrt 1

• sqrt 3, sqrt 2, sqrt 1

In which quadrant are both x and y values negative for the special triangles?

• Fourth quadrant

• First quadrant

• Second quadrant

• Third quadrant

What happens to the x values when the points are flipped over?
