Learn how to evaluate the three trig functions given a trig equation and constraint

The video tutorial explains the concept of cotangent and how to create triangles with specific constraints. It discusses the importance of considering positive and negative values in the context of an X&Y axis. The tutorial also covers the secant function and its relation to cosine, identifying the quadrants where cosine is negative. The Pythagorean theorem is applied to determine triangle properties, and the simplification of trigonometric functions like sine, cosine, and tangent is demonstrated.
