Solución

- 2 sec (2 (\frac{3 π}{4}))

Solución

Sin definir

Pasos de solución

- 2 sec (2 (\frac{3 π}{4}))

= - 2 sec (2 \cdot \frac{3 π}{4})

Simplificar:

2 \cdot \frac{3 π}{4} = \frac{3 π}{2}

2 \cdot \frac{3 π}{4}

Multiplicar fracciones:

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

= \frac{3 π 2}{4}

Multiplicar los numeros:

3 \cdot 2 = 6

= \frac{6 π}{4}

Eliminar los terminos comunes:

2

= \frac{3 π}{2}

= - 2 sec (\frac{3 π}{2})

Re-escribir usando identidades trigonométricas:

sec (\frac{3 π}{2}) =

Sin definir

sec (\frac{3 π}{2})

Utilizar la identidad trigonométrica básica:

sec (x) = \frac{1}{cos ( x )}

= \frac{1}{cos ( \frac{3 π}{2} )}

Simplificar

\frac{1}{cos ( \frac{3 π}{2} )} :

Sin definir

\frac{1}{cos ( \frac{3 π}{2} )}

cos (\frac{3 π}{2}) = 0

= \frac{1}{0}

\frac{x}{0}

no está definida

= Sin definir

= Sin definir

= Sin definir
