How to evaluate the six trig functions when given a constraint and value

The video tutorial explains how to solve a trigonometry problem involving secant and cotangent. It begins by setting up a triangle using the secant value and calculating the third side using the Pythagorean theorem. The instructor discusses the implications of positive and negative roots and how they affect the triangle's configuration. The correct triangle is chosen based on the constraint that cotangent is less than zero. The lesson concludes with final calculations of sine, cosine, and tangent for the chosen triangle.

What is the significance of the constraint that cotangent of Theta is less than zero?

How do you determine which triangle to use based on the cotangent value?
