inverse oflaplace 4/(s^2+1)

inverse laplace

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

4 sin (t)

Solution steps

L^{- 1} {\frac{4}{s ^{2} + 1}}

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

Use the constant multiplication property of Inverse Laplace Transform:

For function

f (t)

and constant

a : L^{- 1} {a \cdot f (t)} = a \cdot L^{- 1} {f (t)}

= 4 L^{- 1} {\frac{1}{s ^{2} + 1 ^{2}}}

Use Inverse Laplace Transform table:

L^{- 1} {\frac{a}{s ^{2} + a ^{2}}} = sin (a t)

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

= 4 sin (t)

\frac{d y}{d t} = t y

\frac{d y}{d x}, y = 5 x

x^{2} y^{^{''}} - 7 x y^{^{'}} + 7 y = 13 x^{\frac{1}{2}}

\frac{\partial}{\partial y} ((x^{2} - y^{2}) e^{- x^{2} - y^{2}})

x \to - \infty lim (3^{2 x})
