tanh(mL)=0.99

解

tanh (m L) = 0.99

解

L = \frac{ln ( \frac{1.99}{0.01} )}{2 m}

解答ステップ

tanh (m L) = 0.99

三角関数の公式を使用して書き換える

tanh (m L) = 0.99

双曲線の公式を使用する:

tanh (x) = \frac{e ^{x} - e ^{- x}}{e ^{x} + e ^{- x}}

\frac{e ^{m L} - e ^{- m L}}{e ^{m L} + e ^{- m L}} = 0.99

\frac{e ^{m L} - e ^{- m L}}{e ^{m L} + e ^{- m L}} = 0.99

\frac{e ^{m L} - e ^{- m L}}{e ^{m L} + e ^{- m L}} = 0.99 : L = \frac{ln ( \frac{1.99}{0.01} )}{2 m} {m < 0 or m > 0}

\frac{e ^{m L} - e ^{- m L}}{e ^{m L} + e ^{- m L}} = 0.99

以下で両辺を乗じる:

e^{m L} + e^{- m L}

\frac{e ^{m L} - e ^{- m L}}{e ^{m L} + e ^{- m L}} (e^{m L} + e^{- m L}) = 0.99 (e^{m L} + e^{- m L})

簡素化

e^{m L} - e^{- m L} = 0.99 (e^{m L} + e^{- m L})

両辺から

0.99 (e^{m L} + e^{- m L})

を引く

e^{m L} - e^{- m L} - 0.99 (e^{m L} + e^{- m L}) = 0.99 (e^{m L} + e^{- m L}) - 0.99 (e^{m L} + e^{- m L})

e^{2.64665 \dots} e^{2.64665 \dots} = e^{5.29330 \dots}

e^{2.64665 \dots} e^{2.64665 \dots}

指数の規則を適用する:

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

e^{2.64665 \dots} e^{2.64665 \dots} = e^{2.64665 \dots + 2.64665 \dots}

= e^{2.64665 \dots + 2.64665 \dots}

数を足す:

2.64665 \dots + 2.64665 \dots = 5.29330 \dots

= e^{5.29330 \dots}

= e^{5.29330 \dots} - 1

= \frac{e ^{5.29330 \dots} - 1}{e ^{2.64665 \dots}}

e^{5.29330 \dots} = 198.99999 \dots

= \frac{198.99999 \dots - 1}{e ^{2.64665 \dots}}

数を引く:

198.99999 \dots - 1 = 197.99999 \dots

= \frac{197.99999 \dots}{e ^{2.64665 \dots}}

e^{2.64665 \dots} = 14.10673 \dots

= \frac{197.99999 \dots}{14.10673 \dots}

数を割る:

\frac{197.99999 \dots}{14.10673 \dots} = 14.03584 \dots

= 14.03584 \dots

= \frac{14.03584 \dots}{14.17762 \dots}

数を割る:

\frac{14.03584 \dots}{14.17762 \dots} = 0.99

= 0.99

= 0.99

0.99 = 0.99
