Learn where the formula for the Law of Sines comes from

The video tutorial explores trigonometric relationships in triangles, focusing on the sine function. It begins by examining the height of a triangle and establishing sine relationships for different angles. The instructor then solves for the height in terms of sine expressions and equates them to derive the sine rule, highlighting the commonality of the height in both equations. The session concludes with a brief mention of further steps involving another angle, which are not covered in this tutorial.

What is the significance of the common height H in the relationships derived from the two triangles?

Describe the process of setting the two expressions for height H equal to each other.
