laplacetransform 3sin(3t)

laplace transform

3 sin (3 t)

\frac{9}{s ^{2} + 9}

Solution steps

L {3 sin (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 {sin (3 t)}

L {sin (3 t)} : \frac{3}{s ^{2} + 9}

= 3 \cdot \frac{3}{s ^{2} + 9}

Refine

3 \frac{3}{s ^{2} + 9} : \frac{9}{s ^{2} + 9}

= \frac{9}{s ^{2} + 9}
