Inverse laplace transform of H(s) = 1/(s+4)^2

ziro4ka [17]

Answer:

Inverse Laplace of $\frac{1}{(S+4)^2}$ will be $te^{-4t}$

Step-by-step explanation:

We have to find the inverse Laplace transform of $H(S)=\frac{1}{(S+4)^2}$

We know that of $\frac{1}{s+4}$ is $e^{-4t}$

As in H(s) there is square of $s+4$

So i inverse Laplace there will be multiplication of t

So the inverse Laplace of $\frac{1}{(s+4)^2}$ will be $te^{-4t}$

$L^{-1}\frac{1}{(S+4)^2}=te^{-4t}$

I need help with the steps. The answer is (5,2)

Elden [556K]

So with this, I will be using the substitution method. With the first equation, substitute (y+3) into the x variable and solve for y:

$y+3+y=7\\2y+3=7\\2y=4\\y=2$

Next, now that we have the value of y, substitute it into either equation to solve for x:

$x+2=7\\x=5\\\\x=2+3\\x=5$

<u>And this is how you get your final answer (5,2).</u>
