laplacetransform 3e^{-3t}

laplace transform

3 e^{- 3 t}

\frac{3}{s + 3}

Solution steps

L {3 e^{- 3 t}}

Use the constant multiplication property of Laplace Transform:

For function

f (t)

and constant

a : L {a \cdot f (t)} = a \cdot L {f (t)}

= 3 L {e^{- 3 t}}

L {e^{- 3 t}} : \frac{1}{s + 3}

= 3 \cdot \frac{1}{s + 3}

Refine

3 \frac{1}{s + 3} : \frac{3}{s + 3}

= \frac{3}{s + 3}
