Learning to find the reference angle in the second quadrant

The video tutorial explains the concept of reference angles, focusing on their calculation and representation in different quadrants. It begins with an introduction to quadrants and the definition of a reference angle, often denoted as Theta prime. The instructor demonstrates how to graph angles, specifically using 2π/3 as an example, and explains the importance of visualizing angles to understand their positions. The tutorial then covers the calculation of reference angles in radians, particularly in the second quadrant, using the formula Theta prime equals π minus Theta. The process of ensuring common denominators for subtraction is also highlighted.
