2) Halla el resultado de la siguiente expresión: \( B=\left(\cos 270^{\circ}\right)^{\operatorname{sen} 90^{\circ}}-\frac{\tan 360^{\circ}}{\cos 0^{\circ}}+5\left(\sec 180^{\circ}\right)^{\cot 270^{\circ}} \)

Step-by-step Solution
Para resolver la expresión \( B=\left(\cos 270^{\circ}\right)^{\operatorname{sen} 90^{\circ}}-\frac{\tan 360^{\circ}}{\cos 0^{\circ}}+5\left(\sec 180^{\circ}\right)^{\cot 270^{\circ}} \), primero calculamos cada una de las funciones trigonométricas involucradas:
1. \( \cos 270^{\circ} = 0 \)
2. \( \sin 90^{\circ} = 1 \)
3. \( \tan 360^{\circ} = 0 \)
4. \( \cos 0^{\circ} = 1 \)
5. \( \sec 180^{\circ} = -1 \)
6. \( \cot 270^{\circ} = 0 \)
Ahora sustituimos estos valores en la expresión original:
\[ B = (0)^1 - \frac{0}{1} + 5(-1)^0 \]
\[ B = 0 - 0 + 5(1) \]
\[ B = 0 + 5 \]
\[ B = 5 \]
Por lo tanto, el resultado de la expresión es \( B = 5 \).
Quick Answer
El resultado de la expresión es \( B = 5 \).
