-cosh(sech(x))(sech(x)tanh(x))=0

- cosh (sech (x)) (sech (x) tanh (x)) = 0

x = 0

Solution steps

- cosh (sech (x)) (sech (x) tanh (x)) = 0

Rewrite using trig identities

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

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

x = 0

\frac{sin ( 9 7 ^{\circ} )}{14} = \frac{sin ( b )}{10}

tan (x) = \frac{5 + cos ( x )}{6 sin ( x ) cos ( x )}

cos (x - 1) = \frac{1}{2}, 0^{\circ} \leq x \leq 36 0^{\circ}

cos (t) = \frac{21}{29}

cos (x) = sin (x - \frac{π}{3})
