Learning to Find the Angle Given the Inverse Sine of a Value

The video tutorial explains the concept of sine inverse, focusing on how to determine angles with specific sine values using inverse operations. It covers the unit circle, reflections, and domain restrictions, emphasizing the importance of radians. The tutorial concludes with methods to verify answers, highlighting the angle of -π/6 or -30 degrees as a solution.

What is the purpose of using the sine inverse function?

• To convert degrees to radians

• To determine the angle given its sine value

• To find the cosine of an angle

• To calculate the tangent of an angle

In which quadrant of the unit circle is the sine of an angle equal to 1/2?

• Fourth quadrant

• Third quadrant

• First quadrant

• Second quadrant

What is the angle in radians where the sine is -1/2?

• -π/3

• π/3

• -π/6

• π/6

What is the domain restriction for the sine inverse function?

• 0 to π
