sec^2(arctan(3))+csc^2(arccot(4))

Solución

sec^{2} (arctan (3)) + csc^{2} (arccot (4))

27

Pasos de solución

sec^{2} (arctan (3)) + csc^{2} (arccot (4))

Re-escribir usando identidades trigonométricas:

csc (arccot (4)) = \frac{1 + 4 ^{2}}{1 + 4 ^{2}}

Usar la siguiente identidad:

csc (arccot (x)) = \frac{1 + x ^{2}}{1 + x ^{2}}

= \frac{1 + 4 ^{2}}{1 + 4 ^{2}}

= sec^{2} (arctan (3)) + (\frac{1 + 4 ^{2}}{1 + 4 ^{2}})^{2}

Simplificar

= sec^{2} (arctan (3)) + 17

Re-escribir usando identidades trigonométricas:

sec (arctan (3)) = 10

sec (arctan (3))

Re-escribir usando identidades trigonométricas:

sec (arctan (3)) = 1 + 3^{2}

Usar la siguiente identidad:

sec (arctan (x)) = 1 + x^{2}

= 1 + 3^{2}

= 1 + 3^{2}

Simplificar

= 10

= (10)^{2} + 17

Simplificar

(10)^{2} + 17 : 27

(10)^{2} + 17

(10)^{2} = 10

(10)^{2}

Aplicar las leyes de los exponentes:

a = a^{\frac{1}{2}}

= (1 0^{\frac{1}{2}})^{2}

Aplicar las leyes de los exponentes:

(a^{b})^{c} = a^{b c}

= 1 0^{\frac{1}{2} \cdot 2}

\frac{1}{2} \cdot 2 = 1

\frac{1}{2} \cdot 2

Multiplicar fracciones:

a \cdot \frac{b}{c} = \frac{a \cdot b}{c}

= \frac{1 \cdot 2}{2}

Eliminar los terminos comunes:

2

= 1

= 10

= 10 + 17

Sumar:

10 + 17 = 27

= 27

= 27
