Question

please give clear solution with all the necessary work!

Inverse Laplace transforms can be found using the linearity property of transforms and a reference table. Find the Inverse Laplace transform of 

\[ F(s) = \frac{-4s - 2}{s^2 - 2s + 26}. \]

Show all the work needed to rewrite the functions. Express the inverse Laplace transform as a function of \( t \). [Hint: you may need to first complete the square in the denominator!]

\[ f(t) = \underline{\hspace{3cm}} \]

Expert Solution
Step 1: Define the linearity property of Inverse Laplace Transform:

The linearity property of Inverse Laplace Transform:

L to the power of negative 1 end exponent open curly brackets a times f open parentheses s close parentheses plus b times g open parentheses s close parentheses close curly brackets equals a times L to the power of negative 1 end exponent open curly brackets f open parentheses s close parentheses close curly brackets plus b times L to the power of negative 1 end exponent open curly brackets g open parentheses s close parentheses close curly brackets

Where a and b is the constant.

And the Inverse Laplace transform identities:

1). L to the power of negative 1 end exponent open curly brackets fraction numerator s minus a over denominator open parentheses s minus a close parentheses squared plus b squared end fraction close curly brackets equals e to the power of a t end exponent cos open parentheses b t close parentheses

2). L to the power of negative 1 end exponent open curly brackets fraction numerator 1 over denominator open parentheses s minus a close parentheses squared plus b squared end fraction close curly brackets equals 1 over b e to the power of a t end exponent sin open parentheses b t close parentheses
