Evaluate the composition of sine and sine inverse

The video tutorial explains how to calculate the sine of π/6 using a calculator, emphasizing the importance of following the order of operations. It revisits the concept of the unit circle and identifies angles that produce a sine value of 1/2. The tutorial also covers inverse sine and the restrictions of quadrants for sine, cosine, and tangent functions, helping students understand which angles are valid for these trigonometric functions.

Explain the order of operations when solving trigonometric problems.

What is the cosine restriction when finding the inverse?
