Learn how to evaluate the six trig functions given an equation and constraint

The video tutorial explores the variability in drawing triangles based on given trigonometric information, focusing on cosine and cotangent functions. It discusses how different triangles can be drawn, the importance of constraints like cotangent negativity, and the role of reference angles. The tutorial also reviews homework assignments related to these concepts and provides a detailed analysis of cosine in different quadrants, concluding with final trigonometric calculations.

Explain the relationship between cosine and the position of the triangle in the quadrants.

What is the significance of the hypotenuse being positive in trigonometric functions?
