inverse of f(x)= x/(x^2-a^2)

inverse

f (x) = \frac{x}{x ^{2} - a ^{2}}

\frac{1 + 1 + 4 a ^{2} x ^{2}}{2 x}, \frac{1 - 1 + 4 a ^{2} x ^{2}}{2 x}

Solution steps

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

Replace

x

with

y

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

Solve for

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

\frac{1 + 1 + 4 a ^{2} x ^{2}}{2 x}, \frac{1 - 1 + 4 a ^{2} x ^{2}}{2 x}
