How to Determine the Angle Given the Value of Cosine

The video tutorial explains the concept of Theta and how to find the cosine of an angle. It describes cosine as the X coordinate of an angle and demonstrates how to determine which angle has a cosine of 1/2, identifying it as 60 degrees or π/3. The tutorial emphasizes understanding the relationship between angles and their cosine values.
