Inverse Laplace Transform of (2s+1)/(s^2+16)

In summary, an Inverse LaPlace Transform is a mathematical operation that reverses the process of a LaPlace Transform, converting a function from the frequency domain back to the time domain. This can be done using a table of known pairs, algebraic manipulation, or computational software. The purpose of this transformation is to solve differential equations and other complex mathematical problems. It has various applications in engineering, physics, and mathematics, but it also has limitations such as not being able to transform all functions and potential errors in the transformation process.

Homework Statement



Determine the inverse Laplace transform of the given function

F(s) = (2s+1) / (s^2 + 16 )

Homework Equations



the LaPlace transform of different functions

The Attempt at a Solution



I divide the above equation into 2 fractions one with the 2s in the numerator and the other fraction with the 1 in the numerator. I know what the inverse Laplace transform of the 2s is but not what the (1) / (s^2+16).
