sinh(pi)-sinh(-pi)

sinh (π) - sinh (- π)

\frac{e ^{2 π} - 1}{e ^{π}}

Decimal Notation

23.09747 \dots

Solution steps

sinh (π) - sinh (- π)

Use the following property:

sinh (- x) = - sinh (x)

sinh (- π) = - sinh (π)

= sinh (π) - (- sinh (π))

Simplify

= 2 sinh (π)

Rewrite using trig identities:

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

sinh (π)

Use the Hyperbolic identity:

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

= \frac{e ^{π} - e ^{- π}}{2}

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

\frac{e ^{π} - e ^{- π}}{2}

Apply exponent rule:

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

= \frac{e ^{π} - \frac{1}{e ^{π}}}{2}

Join

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

e^{π} - \frac{1}{e ^{π}}

Convert element to fraction:

e^{π} = \frac{e ^{π} e ^{π}}{e ^{π}}

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

Since the denominators are equal, combine the fractions:

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

= \frac{e ^{π} e ^{π} - 1}{e ^{π}}

e^{π} e^{π} - 1 = e^{2 π} - 1

e^{π} e^{π} - 1

e^{π} e^{π} = e^{2 π}

e^{π} e^{π}

Apply exponent rule:

a^{b} \cdot a^{c} = a^{b + c}

e^{π} e^{π} = e^{π + π}

= e^{π + π}

Add similar elements:

π + π = 2 π

= e^{2 π}

= e^{2 π} - 1

= \frac{e ^{2 π} - 1}{e ^{π}}

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

Apply the fraction rule:

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

= \frac{e ^{2 π} - 1}{e ^{π} \cdot 2}

= \frac{e ^{2 π} - 1}{2 e ^{π}}

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

Simplify

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

2 \cdot \frac{e ^{2 π} - 1}{2 e ^{π}}

Multiply fractions:

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

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

Cancel the common factor:

2

= \frac{e ^{2 π} - 1}{e ^{π}}

= \frac{e ^{2 π} - 1}{e ^{π}}

2 arcsin (\frac{1}{2})

tan (arccos (0.95)) - tan (arccos (0.8))

2 sin (3 8^{\circ}) cos (3 8^{\circ})

600 - \frac{220}{sin ( 3 7 ^{\circ} )} sin (3 7^{\circ})

tan (\frac{10}{6})
