How to Math - Determine what quadrant an angle lies in - Free Math Help Videos

The video tutorial explains how to determine the quadrant of an angle using radians and fractions. It begins with an introduction to angle quadrants and visualization techniques. The instructor then demonstrates how to simplify fractions to relate them to quadrants. The concept of radians is explained, including how they correspond to the circle's radius and how to use them to identify quadrants. The tutorial concludes with a summary of the methods for determining angle quadrants.

How can you simplify a fraction to determine its quadrant?
