hence, after substituting (7.1) into (7.20), and again substituting the resulting
equation into (7.21), we get
We can invert a nonlinear function,
represented by a power series
up to the third-order term
into
by using the conversion formulas [KO91], [WM95] reported below
Therefore,
is given by
and combining (7.28) with (7.1), taking only the first three power terms, we
get
