Inverse Laplace Transform for Negative a^2?

In summary, a specific Laplace transform is a mathematical tool used to convert a function of time into a function of complex frequency, commonly used in engineering, physics, and mathematics to solve differential equations and analyze systems. It is a subset of the general Laplace transform and is used to simplify the analysis of complex systems, allowing for the use of complex analysis techniques and providing more accurate solutions. Some advantages of using a specific Laplace transform include the ability to solve complex differential equations, efficient calculation of system responses, and handling initial and boundary conditions with ease. Its applications include control systems, signal processing, circuit analysis, and the solution of partial differential equations and systems with time delays.

There are lots of tables out there for finding the inverse laplace transform of:

[tex]\frac{1}{(s+b)^{2}+a^{2}}[/tex]

or

[tex]\frac{s}{(s+b)^{2}+a^{2}}[/tex]

but what if [tex]a^{2}[/tex] is negative?

I don't know what useful formula I should split it up into.

If a2 is negative then you may further factored the denominator. Then you formed a partial fraction for the whole expression.

e.g. let a2=-c2.

(s+b)2+a2=(s+b+c)(s+b-c)
