Step-by-step Solution
Para simplificar la expresión \( \frac{\sec x \cot x}{\tan x} \), primero recordemos las definiciones de las funciones trigonométricas involucradas:
- \( \sec x = \frac{1}{\cos x} \)
- \( \cot x = \frac{\cos x}{\sin x} \)
- \( \tan x = \frac{\sin x}{\cos x} \)
Ahora, sustituimos estas definiciones en la expresión:
\[
\frac{\sec x \cot x}{\tan x} = \frac{\frac{1}{\cos x} \cdot \frac{\cos x}{\sin x}}{\frac{\sin x}{\cos x}}
\]
Simplificamos el numerador:
\[
\frac{1 \cdot \cos x}{\cos x \cdot \sin x} = \frac{1}{\sin x}
\]
Ahora, la expresión se convierte en:
\[
\frac{\frac{1}{\sin x}}{\frac{\sin x}{\cos x}} = \frac{1}{\sin x} \cdot \frac{\cos x}{\sin x} = \frac{\cos x}{\sin^2 x}
\]
Por lo tanto, la expresión simplificada es:
\[
\frac{\cos x}{\sin^2 x}
\]
Esto se puede escribir también como:
\[
\cot x \csc x
\]
Así que la forma simplificada de la expresión original es:
\[
\cot x \csc x
\]
Quick Answer
La expresión simplificada es \( \cot x \csc x \).
