sinh(-1/2)

sinh (- \frac{1}{2})

- \frac{e ^{\frac{1}{2}} e - 1}{2 e}

Decimal Notation

- 0.52109 \dots

Solution steps

sinh (- \frac{1}{2})

Use the following property:

sinh (- x) = - sinh (x)

sinh (- \frac{1}{2}) = - sinh (\frac{1}{2})

= - sinh (\frac{1}{2})

Rewrite using trig identities:

sinh (\frac{1}{2}) = \frac{e ^{\frac{1}{2}} e - 1}{2 e}

sinh (\frac{1}{2})

Use the Hyperbolic identity:

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

= \frac{e ^{\frac{1}{2}} - e ^{- \frac{1}{2}}}{2}

\frac{e ^{\frac{1}{2}} - e ^{- \frac{1}{2}}}{2} = \frac{e ^{\frac{1}{2}} e - 1}{2 e}

\frac{e ^{\frac{1}{2}} - e ^{- \frac{1}{2}}}{2}

Apply exponent rule:

a^{- b} = \frac{1}{a ^{b}}

= \frac{e ^{\frac{1}{2}} - \frac{1}{e}}{2}

Join

e^{\frac{1}{2}} - \frac{1}{e} : \frac{e ^{\frac{1}{2}} e - 1}{e}

e^{\frac{1}{2}} - \frac{1}{e}

Convert element to fraction:

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

= \frac{e ^{\frac{1}{2}} e}{e} - \frac{1}{e}

Since the denominators are equal, combine the fractions:

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

= \frac{e ^{\frac{1}{2}} e - 1}{e}

= \frac{\frac{e ^{\frac{1}{2}} e - 1}{e}}{2}

Apply the fraction rule:

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

= \frac{e ^{\frac{1}{2}} e - 1}{e \cdot 2}

= \frac{e ^{\frac{1}{2}} e - 1}{2 e}

= - \frac{e ^{\frac{1}{2}} e - 1}{2 e}
