expand ((1+e^{-2s})^2)/(s+2)

expand

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

\frac{1 + 2 e ^{- 2 s} + e ^{- 4 s}}{s + 2}

Solution steps

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

(1 + e^{- 2 s})^{2} = 1 + 2 e^{- 2 s} + e^{- 4 s}

= \frac{1 + 2 e ^{- 2 s} + e ^{- 4 s}}{s + 2}

e^{x} (x^{2} - x + 1)

\frac{\partial}{\partial y} (3 e^{y}) + e^{y} (5 x + 3 y)

e^{x} (1 - x)

2 (11 - 5)

2 (x + y) d y
