Solving trig equations with no constraints

The video tutorial explains how to solve cosine equations, focusing on the interval from 0 to 2π. It discusses using the unit circle to find solutions where cosine equals 1/2, specifically at π/3 and 5π/3. The tutorial highlights the continuous nature of the cosine graph, leading to infinite solutions without constraints. It introduces the concept of coterminal angles and how to express solutions using 2πN, where N is a variable representing the number of rotations around the circle.
