laplacetransform 2(t+2)

laplace transform

2 (t + 2)

\frac{2}{s ^{2}} + \frac{4}{s}

Solution steps

L {2 (t + 2)}

Expand

2 (t + 2) : 2 t + 4

= L {2 t + 4}

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)}

= 2 L {t} + L {4}

L {t} : \frac{1}{s ^{2}}

L {4} : \frac{4}{s}

= 2 \cdot \frac{1}{s ^{2}} + \frac{4}{s}

Refine

2 \frac{1}{s ^{2}} + \frac{4}{s} : \frac{2}{s ^{2}} + \frac{4}{s}

= \frac{2}{s ^{2}} + \frac{4}{s}
