inverse of (a^x-a^{-x})/2

inverse

\frac{a ^{x} - a ^{- x}}{2}

\frac{ln ( x + x ^{2} + 1 )}{ln ( a )}, \frac{ln ( x - x ^{2} + 1 )}{ln ( a )}

Solution steps

y = \frac{a ^{x} - a ^{- x}}{2}

Replace

x

with

y

x = \frac{a ^{y} - a ^{- y}}{2}

Solve for

y, x = \frac{a ^{y} - a ^{- y}}{2}

\frac{ln ( x + x ^{2} + 1 )}{ln ( a )}, \frac{ln ( x - x ^{2} + 1 )}{ln ( a )}
