Solving trigonometric equation by using reciprocal function

The video tutorial explains how to solve for X within the interval of 0 to 2π by isolating the cosecant function and using the unit circle. It covers the relationship between trigonometric functions and their reciprocals, focusing on finding when the sine value equals sqrt 3/2. The tutorial concludes with a discussion on interval restrictions and potential variations in problem conditions.

Identify the two points on the unit circle where the sine value equals sqrt 3/2.

Why is it important to restrict the answers between 0 and 2π in this problem?
