sinh(pi/6 i)

Solución

sinh (\frac{π}{6} i)

i sin (\frac{π}{6})

Pasos de solución

sinh (\frac{π}{6} i)

Simplificar:

\frac{π}{6} i = \frac{πi}{6}

\frac{π}{6} i

Multiplicar fracciones:

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

= \frac{πi}{6}

= sinh (\frac{πi}{6})

Re-escribir usando identidades trigonométricas:

i sin (\frac{π}{6})

sinh (\frac{πi}{6})

Utilizar la identidad hiperbólica:

sinh (x) = \frac{e ^{x} - e ^{- x}}{2}

= \frac{e ^{\frac{πi}{6}} - e ^{- \frac{πi}{6}}}{2}

Simplificar

\frac{e ^{\frac{πi}{6}} - e ^{- \frac{πi}{6}}}{2} : \frac{- cos ( - \frac{π}{6} ) + cos ( \frac{π}{6} )}{2} + i \frac{- sin ( - \frac{π}{6} ) + sin ( \frac{π}{6} )}{2}
