inverse oflaplace ((e^{-s}))/(s(s+1))

inverse laplace

\frac{( e ^{- s} )}{s ( s + 1 )}

H (t - 1) (1 - e^{- t + 1})

Solution steps

L^{- 1} {\frac{( e ^{- s} )}{s ( s + 1 )}}

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

L^{- 1} {\frac{1}{s ( s + 1 )}} : H (t) - e^{- t}

= H (t - 1) (H (t - 1) - e^{- (t - 1)})

H (t - 1) = {01 t < 1 t \geq 1

= {0 1 - e^{- t + 1} t < 1 t \geq 1

= H (t - 1) (1 - e^{- t + 1})

\frac{d}{d x} (128 sin (2 x))

y = (x^{2} + 4)^{2}

x^{2}, 0, - 1, 2

\frac{d}{d x} (sin (π x^{2}))

x \to 0 + lim (\frac{1}{x ln ( x ^{9} )})
