Trigonometric Derivatives and Identities

The video tutorial explains the derivatives of basic trigonometric functions, starting with sine and cosine. It then demonstrates how to find the derivative of tangent using the quotient rule, expressing tangent as sine over cosine. The tutorial continues with the derivative of cotangent, again using the quotient rule, and highlights the use of trigonometric identities to simplify results.
