What are the quotient identities

The video tutorial introduces quotient identities using the unit circle. It explains how sine, cosine, and tangent are derived from the unit circle, with a focus on the relationship between these trigonometric functions. The tutorial further explores quotient identities by substituting sine and cosine into the tangent function. Additionally, it introduces reciprocal identities, explaining how cotangent is the reciprocal of tangent. The video provides a concise overview of these mathematical concepts, emphasizing their interconnections.
