Small Perturbation Solution

The small perturbation solution refers to an analytical solution
where only a small change (or several small changes) occurs.
In this case, it refers to a case where only a ``small shock''
occurs, which is up to

*M*_{x}=1.3.
This approach had a major significance and usefulness at a time
when personal computers were not available.
Now, during the writing of this version of the book, this
technique is used mostly in obtaining analytical expressions for
simplified models.
This technique also has an academic value and therefore will be
described in the next version (0.5.x series).

The strength of the shock wave is defined as

By using equation (

5.23) transforms equation
(

5.39) into

or by utilizing equation (

5.24)
the following is obtained:
