Given the Value of Secant Find the Angle

The video tutorial explains the concept of secant in trigonometry, highlighting its reciprocal relationship with cosine. It discusses the unit circle and key angles such as π/6, π/4, and π/3. The tutorial demonstrates how to find the angle where secant equals two by using cosine, emphasizing the interchangeability of these trigonometric functions.

Explain how to find the angle theta when cosine equals 1/2.

What is the angle measure corresponding to secant of theta equals two?
