Pasos de solución

\frac{cosh ( 0.2 m )}{cosh ( 0.4 m )} = 0.6

Re-escribir usando identidades trigonométricas

\frac{cosh ( 0.2 m )}{cosh ( 0.4 m )} = 0.6

Utilizar la identidad hiperbólica:

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

\frac{\frac{e ^{0.2 m} + e ^{- 0.2 m}}{2}}{\frac{e ^{0.4 m} + e ^{- 0.4 m}}{2}} = 0.6

\frac{\frac{e ^{0.2 m} + e ^{- 0.2 m}}{2}}{\frac{e ^{0.4 m} + e ^{- 0.4 m}}{2}} = 0.6

\frac{\frac{e ^{0.2 m} + e ^{- 0.2 m}}{2}}{\frac{e ^{0.4 m} + e ^{- 0.4 m}}{2}} = 0.6 : m = ln (0.03402 \dots), m = ln (29.38731 \dots)

\frac{\frac{e ^{0.2 m} + e ^{- 0.2 m}}{2}}{\frac{e ^{0.4 m} + e ^{- 0.4 m}}{2}} = 0.6

Multiplicar ambos lados por

\frac{e ^{0.4 m} + e ^{- 0.4 m}}{2}

\frac{\frac{e ^{0.2 m} + e ^{- 0.2 m}}{2}}{\frac{e ^{0.4 m} + e ^{- 0.4 m}}{2}} \cdot \frac{e ^{0.4 m} + e ^{- 0.4 m}}{2} = 0.6 \cdot \frac{e ^{0.4 m} + e ^{- 0.4 m}}{2}

Simplificar

\frac{e ^{0.2 m} + e ^{- 0.2 m}}{2} = \frac{0.6 ( e ^{0.4 m} + e ^{- 0.4 m} )}{2}

Aplicar las leyes de los exponentes

\frac{e ^{0.2 m} + e ^{- 0.2 m}}{2} = \frac{0.6 ( e ^{0.4 m} + e ^{- 0.4 m} )}{2}

Aplicar las leyes de los exponentes:

\frac{( e ^{m} ) ^{0.2} + ( e ^{m} ) ^{- 0.2}}{2} = \frac{0.6 ( ( e ^{m} ) ^{0.4} + ( e ^{m} ) ^{- 0.4} )}{2}

\frac{( e ^{m} ) ^{0.2} + ( e ^{m} ) ^{- 0.2}}{2} = \frac{0.6 ( ( e ^{m} ) ^{0.4} + ( e ^{m} ) ^{- 0.4} )}{2}

Re escribir la ecuación con

e^{m} = u

\frac{( u ) ^{0.2} + ( u ) ^{- 0.2}}{2} = \frac{0.6 ( ( u ) ^{0.4} + ( u ) ^{- 0.4} )}{2}

Resolver

\frac{u ^{0.2} + u ^{- 0.2}}{2} = \frac{0.6 ( u ^{0.4} + u ^{- 0.4} )}{2} : u = 0.03402 \dots, u = 29.38731 \dots

\frac{u ^{0.2} + u ^{- 0.2}}{2} = \frac{0.6 ( u ^{0.4} + u ^{- 0.4} )}{2}

Multiplicar ambos lados por
