Solving for sine with no constraints

The video tutorial explains how to solve trigonometric equations without interval restrictions. It begins by isolating the sine function and solving for X. The unit circle is used to find angle solutions, and the concept of graphing sine is introduced to understand infinite solutions. The tutorial concludes with an explanation of coterminal angles and how to express general solutions by adding multiples of 2π.
