Evaluate for theta between 0 and 2pi

The video tutorial explains when trigonometric functions are undefined, focusing on division by zero. It discusses the cosecant function, represented as 1/y, and how to determine when the Y coordinate is zero on the unit circle. The tutorial also covers constraints for Theta, specifically between 0 and 2π, excluding these values. It concludes by identifying the angle where the Y coordinate is zero, which is at π radians, and summarizes the process of evaluating trigonometric functions.

• When the angle is greater than 2π

• When dividing by zero
