laplacetransform-3sin(4t)

laplace transform

- 3 sin (4 t)

- \frac{12}{s ^{2} + 16}

Solution steps

L {- 3 sin (4 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 (4 t)}

L {sin (4 t)} : \frac{4}{s ^{2} + 16}

= - 3 \cdot \frac{4}{s ^{2} + 16}

Refine

- 3 \frac{4}{s ^{2} + 16} : - \frac{12}{s ^{2} + 16}

= - \frac{12}{s ^{2} + 16}
