Each expression simplifies to a constant, a single function, or a power of a function. Use fundamental identities to simplify each expression.

Trigonometric Identities

Trigonometric identities are equations that involve trigonometric functions and are true for all values of the variables involved. Fundamental identities, such as the Pythagorean identities, reciprocal identities, and quotient identities, serve as the foundation for simplifying trigonometric expressions. Understanding these identities is crucial for manipulating and simplifying expressions like (csc θ sec θ)/cot θ.

Reciprocal Functions

Reciprocal functions in trigonometry refer to pairs of functions that are inverses of each other. For example, cosecant (csc) is the reciprocal of sine (sin), secant (sec) is the reciprocal of cosine (cos), and cotangent (cot) is the reciprocal of tangent (tan). Recognizing these relationships allows for easier simplification of expressions by substituting one function for its reciprocal.

Quotient Identities

Quotient identities express the relationships between the sine, cosine, and tangent functions. Specifically, tangent is defined as the ratio of sine to cosine (tan θ = sin θ/cos θ), and cotangent is the reciprocal of tangent (cot θ = cos θ/sin θ). Utilizing these identities is essential for simplifying expressions involving cotangent, as seen in the given expression (csc θ sec θ)/cot θ.
