How to Find the Angle when Given the Value of Cosine

The video tutorial explains the concept of cotangent in trigonometry, focusing on its representation as the ratio of x over y on the unit circle. It identifies specific points on the unit circle where cotangent equals 1, particularly at π/4 or 45 degrees. The tutorial also explores cotangent values in other quadrants and emphasizes the importance of constraints that limit the focus to the first quadrant, highlighting the significance of understanding these constraints in solving trigonometric problems.
