inverse oflaplace (e^{-2s})/(s^2+16)

inverse laplace

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

H (t - 2) \frac{1}{4} sin (4 (t - 2))

Solution steps

L^{- 1} {\frac{e ^{- 2 s}}{s ^{2} + 16}}

Apply inverse transform rule:

L^{- 1} {F (s)} = f (t)

then

L^{- 1} {e^{- a s} F (s)} = H (t - a) f (t - a)

Where

H (t)

is Heaviside step function

= H (t - 2) L^{- 1} {\frac{1}{s ^{2} + 16}} (t - 2)

L^{- 1} {\frac{1}{s ^{2} + 16}} : \frac{1}{4} sin (4 t)

= H (t - 2) \frac{1}{4} sin (4 (t - 2))

\int_{- 1}^{1} \frac{1}{2} (9 - 9 x^{2})^{2} d x

\frac{d}{d x} (500 x - 0.5 x - 500)

\int (x + 1) (3 x - 2) d x

\frac{d}{d x} (\frac{x}{x + 1})

\int 8 sin^{2} (x - \frac{π}{12}) d x
