What does the cosecant (csc) represent within a right triangle?

• A. Adjacent/Opposite
• B. Opposite/Hypotenuse
• C. Hypotenuse/Opposite
• D. Hypotenuse/Adjacent

Answer: (C)

The cosecant (csc) is defined in a right triangle as the ratio of the hypotenuse to the length of the opposite side. This relationship is a fundamental aspect of trigonometric functions, specifically for the sine function. The sine of an angle in a right triangle is the ratio of the length of the opposite side to the length of the hypotenuse. The cosecant, as the reciprocal of the sine, thus inverts this ratio, leading to the cosecant being expressed as hypotenuse divided by opposite. For example, if you have a right triangle with an angle θ, the sine function is represented by sin(θ) = opposite/hypotenuse. Consequently, cosecant would be csc(θ) = hypotenuse/opposite. This understanding of cosecant is crucial for solving various problems involving triangles and is foundational for more complex trigonometric concepts.
