How to find all of the solutions to an equation as well as within the unit circle

The video tutorial covers the unit circle, focusing on identifying angles with specific coordinates, particularly π/3. It explains how to find angles with the same Y-coordinate and discusses the concept of coterminal angles, emphasizing the addition of 2π to find all possible solutions. The tutorial aims to help students understand the unit circle and solve trigonometric problems involving angles and coordinates.

What is the angle in radians where the x-coordinate is sqrt(3)/2 on the unit circle?

• π/6

• π/3

• π/2

• π/4

Which of the following is a reflection of the point (1/2, sqrt(3)/2) across the y-axis?

• (sqrt(3)/2, 1/2)

• (1/2, -sqrt(3)/2)

• (-1/2, -sqrt(3)/2)

• (-1/2, sqrt(3)/2)

How do you find coterminal angles?

• Add or subtract π

• Add or subtract 2π

• Multiply by 2π
