laplacetransform f(t)=2(1-e^{-5t})

laplace transform

f (t) = 2 (1 - e^{- 5 t})

\frac{2}{s} - \frac{2}{s + 5}

Solution steps

L {2 (- e^{- 5 t} + 1)}

Expand

2 (1 - e^{- 5 t}) : 2 - 2 e^{- 5 t}

= L {2 - 2 e^{- 5 t}}

Use the linearity property of Laplace Transform:

For functions

f (t), g (t)

and constants

a, b : L {a \cdot f (t) + b \cdot g (t)} = a \cdot L {f (t)} + b \cdot L {g (t)}

= L {2} - 2 L {e^{- 5 t}}

L {2} : \frac{2}{s}

L {e^{- 5 t}} : \frac{1}{s + 5}

= \frac{2}{s} - 2 \cdot \frac{1}{s + 5}

Refine

\frac{2}{s} - 2 \frac{1}{s + 5} : \frac{2}{s} - \frac{2}{s + 5}

= \frac{2}{s} - \frac{2}{s + 5}
