Here are the essential concepts you must grasp in order to answer the question correctly.
Trigonometric Functions
Trigonometric functions relate the angles of a triangle to the lengths of its sides. The primary functions include sine, cosine, tangent, cotangent, secant, and cosecant. Each function has specific definitions based on a right triangle or the unit circle, which are essential for calculating values associated with angles.

Cotangent Function
The cotangent function, denoted as cot(θ), is the reciprocal of the tangent function. It is defined as the ratio of the adjacent side to the opposite side in a right triangle. For example, cot(30°) can be calculated as 1/tan(30°), which helps in determining its value using known trigonometric ratios.

Special Angles in Trigonometry
Certain angles, such as 30°, 45°, and 60°, are known as special angles in trigonometry because their sine, cosine, and tangent values are well-defined and can be easily memorized. For instance, cot(30°) corresponds to a specific value derived from the properties of a 30-60-90 triangle, making it straightforward to compute.
