Grados

x = 68.45488 \dots^{\circ}

Pasos de solución

2 sinh (2 x) - 6 cosh (x) = 0

Re-escribir usando identidades trigonométricas

2 sinh (2 x) - 6 cosh (x) = 0

Utilizar la identidad hiperbólica:

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

2 \cdot \frac{e ^{2 x} - e ^{- 2 x}}{2} - 6 cosh (x) = 0

Utilizar la identidad hiperbólica:

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

2 \cdot \frac{e ^{2 x} - e ^{- 2 x}}{2} - 6 \cdot \frac{e ^{x} + e ^{- x}}{2} = 0

2 \cdot \frac{e ^{2 x} - e ^{- 2 x}}{2} - 6 \cdot \frac{e ^{x} + e ^{- x}}{2} = 0

2 \cdot \frac{e ^{2 x} - e ^{- 2 x}}{2} - 6 \cdot \frac{e ^{x} + e ^{- x}}{2} = 0 : x = ln (3.30277 \dots)

2 \cdot \frac{e ^{2 x} - e ^{- 2 x}}{2} - 6 \cdot \frac{e ^{x} + e ^{- x}}{2} = 0

Sumar

6 \frac{e ^{x} + e ^{- x}}{2}

a ambos lados

2 \cdot \frac{e ^{2 x} - e ^{- 2 x}}{2} - 6 \cdot \frac{e ^{x} + e ^{- x}}{2} + 6 \cdot \frac{e ^{x} + e ^{- x}}{2} = 0 + 6 \cdot \frac{e ^{x} + e ^{- x}}{2}
