Final answer:
The actual formula for cotangent (cot) of an angle (θ) is 1 / Tan(θ).
Step-by-step explanation:
The actual formula for cotangent (cot) of an angle (θ) is 1 / Tan(θ).
Cot(θ) can be defined as the ratio of the adjacent side to the opposite side of a right triangle, which is equal to 1 divided by the tangent of θ. Therefore, the correct option is B) 1 / Tan(θ).
