How to Find the Angle Using Cosine when Given Secant

The video tutorial explains how to find the value of Theta in both degrees and radians, specifically between 0 and 90 degrees and 0 and π/2 radians. It covers the basics of angles, quadrants, and the unit circle. The tutorial introduces secant and its reciprocal function, cosine, to solve for Theta. The solution involves identifying where cosine equals 1/2 in the first quadrant, leading to the conclusion that Theta is π/3 radians or 60 degrees.
