Answer

Explanation:

Step1: Recuerda las definiciones trigonométricas

En el círculo unitario, (x = \cos\theta) y (y=\sin\theta).

Step2: Utiliza la definición de la cotangente

La cotangente se define como (\cot\theta=\frac{\cos\theta}{\sin\theta}).

Step3: Sustituye (x) y (y) en la definición de la cotangente

Sustituyendo (x = \cos\theta) y (y=\sin\theta) en (\cot\theta=\frac{\cos\theta}{\sin\theta}), obtenemos (\cot\theta=\frac{x}{y}).

Answer:

D. (\frac{x}{y})
