inverse of (s+1)/((s-1)^2+1)

inverse

\frac{s + 1}{( s - 1 ) ^{2} + 1}

\frac{2 s + 1 + - 4 s ^{2} + 8 s + 1}{2 s}, \frac{2 s + 1 - - 4 s ^{2} + 8 s + 1}{2 s}

Solution steps

y = \frac{s + 1}{( s - 1 ) ^{2} + 1}

Replace

s

with

y

s = \frac{y + 1}{( y - 1 ) ^{2} + 1}

Solve for

y, s = \frac{y + 1}{( y - 1 ) ^{2} + 1}

\frac{2 s + 1 + - 4 s ^{2} + 8 s + 1}{2 s}, \frac{2 s + 1 - - 4 s ^{2} + 8 s + 1}{2 s}
