Here are the essential concepts you must grasp in order to answer the question correctly.
Trigonometric Functions
Trigonometric functions, such as secant, sine, cosine, and tangent, relate angles to ratios of sides in right triangles. The secant function, specifically, is defined as the reciprocal of the cosine function. Understanding these functions is essential for converting trigonometric expressions into algebraic forms.

Inverse Trigonometric Functions
Inverse trigonometric functions, like arccotangent, are used to find angles when given a ratio. The arccotangent function returns the angle whose cotangent is the given value. This concept is crucial for interpreting expressions involving inverse functions and converting them into algebraic expressions.
