sinh(2pi)

sinh (2 π)

\frac{e ^{4 π} - 1}{2 e ^{2 π}}

Decimal Notation

267.74489 \dots

Solution steps

sinh (2 π)

Use the Hyperbolic identity:

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

= \frac{e ^{2 π} - e ^{- 2 π}}{2}

\frac{e ^{2 π} - e ^{- 2 π}}{2} = \frac{e ^{4 π} - 1}{2 e ^{2 π}}

\frac{e ^{2 π} - e ^{- 2 π}}{2}

Apply exponent rule:

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

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

Join

e^{2 π} - \frac{1}{e ^{2 π}} : \frac{e ^{4 π} - 1}{e ^{2 π}}

e^{2 π} - \frac{1}{e ^{2 π}}

Convert element to fraction:

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

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

Since the denominators are equal, combine the fractions:

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

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

e^{2 π} e^{2 π} - 1 = e^{4 π} - 1

e^{2 π} e^{2 π} - 1

e^{2 π} e^{2 π} = e^{4 π}

e^{2 π} e^{2 π}

Apply exponent rule:

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

e^{2 π} e^{2 π} = e^{2 π + 2 π}

= e^{2 π + 2 π}

Add similar elements:

2 π + 2 π = 4 π

= e^{4 π}

= e^{4 π} - 1

= \frac{e ^{4 π} - 1}{e ^{2 π}}

= \frac{\frac{e ^{4 π} - 1}{e ^{2 π}}}{2}

Apply the fraction rule:

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

= \frac{e ^{4 π} - 1}{e ^{2 π} \cdot 2}

= \frac{e ^{4 π} - 1}{2 e ^{2 π}}

cos^{2} (22. 5^{\circ}) - sin^{2} (22. 5^{\circ})

cos (4 5^{\circ}) cos (3 0^{\circ}) + sin (4 5^{\circ}) sin (3 0^{\circ})

sin (\frac{5 π}{12}) - sin (\frac{π}{12})

cos (8 7^{\circ})

cos (2 \frac{π}{3})
