How to find the inverse of a trig value

The video tutorial explains how to solve for Theta using the cosine inverse function, emphasizing the importance of understanding the unit circle and its quadrants. It discusses finding angles with negative cosine values and highlights the constraints of the cosine inverse function, which only provides one answer within the range of 0 to π.

What is the cosine of Theta when it equals -sqrt(3)/2?

Explain the significance of the unit circle in solving for angles in trigonometry.

What are the two angles in the second and third quadrants where the cosine is negative?

What is the constraint for the inverse of cosine?

When evaluating the inverse cosine, why do you only get one answer?
