Now, the equation () will be satisfied by us, by putting
,
and then it follows from (), () and (), one after the other,
,
.
,
|
|
whose latter values are also in agreement with condition ().
Eventually we derive from (X)
,
,
|
|
and then we only have to satisfy condition (XI).
The first one of the herein summarized relation gives nothing new, while the second and third ones read:
,
|
(110)
|
and
.
|
(111)
|
Now, since by the reported formulas
und
it can be written for (110) and (111)
,
and
,
thus at first we find
,
