What is laplacetransform 1/2 (t-2)^2 ?

The answer to laplacetransform 1/2 (t-2)^2 is (1-2s+2s^2)/(s^3)

laplacetransform 1/2 (t-2)^2

laplace transform

\frac{1}{2} (t - 2)^{2}

\frac{1 - 2 s + 2 s ^{2}}{s ^{3}}

Solution steps

L {\frac{1}{2} (t - 2)^{2}}

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)}

= \frac{1}{2} L {(t - 2)^{2}}

L {(t - 2)^{2}} : \frac{2}{s ^{3}} - \frac{4}{s ^{2}} + \frac{4}{s}

= \frac{1}{2} (\frac{2}{s ^{3}} - \frac{4}{s ^{2}} + \frac{4}{s})

Refine

\frac{1}{2} (\frac{2}{s ^{3}} - \frac{4}{s ^{2}} + \frac{4}{s}) : \frac{1 - 2 s + 2 s ^{2}}{s ^{3}}

= \frac{1 - 2 s + 2 s ^{2}}{s ^{3}}

\frac{\partial}{\partial x} (4 y + x e^{\frac{x}{y}})

\int 7 sec^{2} (x) d x

\int e^{5 x} x d x

\int \frac{2}{x 9 x ^{2} + 1} d x

\int \frac{x ^{2} + 5 x + 7}{x + 3} d x
