Finding the Inverse Using Tangent

The video tutorial covers the concept of tangent in trigonometry, explaining it as the ratio of sine to cosine (y/X) and its representation on the unit circle. It introduces three key coordinate points on the unit circle and demonstrates how to calculate tangent values using these points. The tutorial also addresses the calculation of negative tangent values and the limitations of the inverse tangent function, which is only defined between -π/2 and π/2. Interruptions for announcements are noted but do not detract from the main content.
