Evaluate for Theta Between 0 and 2pi ex 4, tanθ = 0

The video tutorial explains how to evaluate the tangent of an angle on the unit circle, focusing on when the tangent equals zero. It highlights that tangent is the ratio of the X and Y coordinates on the unit circle and emphasizes the importance of the Y coordinate being zero for the tangent to be zero. The tutorial identifies that the angle π is where the tangent equals zero, within the constraints of 0 to 2π.

Why can't the angles 0 and 2π be included in the evaluation of the tangent function?
