Solving trigonometric equations with multiple angles

The video tutorial explains how to solve a cosine equation using the zero product property. It begins by introducing the problem and the concept of the zero product property. The tutorial then demonstrates how to solve the equation by identifying when cosine values are zero or negative one using the unit circle. It further explains how to find all possible solutions by adding multiples of π and 2π. The video concludes with the final solutions and a summary of the steps taken.
