SUMMARY

The discussion focuses on simplifying the inverse Laplace function derived from a circuit analysis of a transmission line, represented as \(\frac{s^2RC+sL}{s^2RC+sL+R}\). The simplification process involves dividing the numerator by the denominator, resulting in the expression \(1 - \frac{R}{s^2RC+sL+R}\). Completing the square in the denominator further aids in the simplification, providing a clearer path to finding the inverse Laplace function.

Homework Statement



Any way to reduce this function for simplification? (Trying to find the reverse Laplace function) I found this function after doing a circuit analysis on a transmission line.

\frac{s^2RC+sL}{s^2RC+sL+R}

Homework Equations



none

The Attempt at a Solution



I couldn't arrive at anything past this

Well, seeing "s^2RC+ sL" in both numerator and denominator, the first thing I would do is divide s^2RC+ sL+ R into s^2RC+ sL. Obviously, it will go into it once with remainder (s^2RC+ sL)- (s^2RC+ sL+ R)= -R.

That is
\frac{s^2RC+ sL}{s^2RC+ sL+ R}= 1-\frac{R}{s^2RC+ sL+ R}

Now, if s is the variable, complete the square in the denominator.
 
holy cow that was quick. Many thanks. I think that works out.
