Morphology
The phrase combines the familiar adjective 'inverse' (meaning reversed or opposite) with the technical noun 'cotangent', so learners who know both words can partly infer it refers to the reversed/undoing operation on the cotangent. However, the precise mathematical sense — the angle whose cotangent equals a given value (arccot) — requires domain knowledge of functions and trigonometry, so the meaning is not fully predictable to a general B1 learner without that background.
Etymology
Inverse cotangent comes from doing the opposite of cotangent. While cotangent turns an angle into a number, the inverse cotangent 'finds the angle' when you have that number.
