Evaluate for theta between 0 and 2pi

The video tutorial explains how to evaluate Theta when the cotangent of Theta equals -1. It begins by defining cotangent as the ratio of the X to Y coordinate. The instructor then explores the quadrants to find where this ratio is negative, focusing on the third quadrant where both coordinates are negative. The tutorial identifies the angles that satisfy the condition, specifically 3π/4, and ensures they fall within the 0 to 2π range. The process is summarized to help viewers understand how to find Theta given a negative cotangent.
