✔ 最佳答案
cos(θ) / cot(θ)= cos(θ) / [ cos(θ) / sin(θ) ]
= sin(θ)

cos(θ)
----------
cot(θ)
...cos(θ)
=------------------
...cos(θ)/sin(θ)
=cos(θ) * sin(θ)/cos(θ)
=sin(θ) answer..//

Do not settle for an incomplete answer.
cos(θ) / cot(θ)
= cos(θ)tan(θ)
= cos(θ)[sin(θ) / cos(θ)]
= sin(θ), θ ≠ kπ/2 for any integer k
The given expression is undefined where θ is equal to any multiple of π/2. Simplifying the expression cannot change that.
