Learn how to evaluate the inverse composition of sine and cosine

The video tutorial focuses on solving trigonometric problems, emphasizing the importance of practice. It guides students through evaluating the cosine of π/3, explaining the coordinate point and its significance. The tutorial then transitions to arcsine, discussing angle restrictions and identifying the correct angle within the restricted domain. The teacher highlights key angles and reinforces the importance of understanding these concepts for exams.

What is the value of cosine of π / 3?

What is the angle when sine is equal to 1/2?

What is the restricted domain for the inverse sine function?

Why is π/6 the only angle that falls within the restriction for the inverse sine function?

What is the significance of the phrase 'Intent wink wink' in the context of the quiz?
