Find the values of
for which
and
are equivalent.
The components are
and
.
Since the components are to be equal, equate
and
.


The general solution of
is
, where
is an integer.
The solution is
, where
is an integer.
Now find the solutions on the interval
.
If
,
.
If
,
.
Thus, the solutions are
and
on the interval
.
\
Therefore, the components will be equivalent when
or
, where
is an integer.
The components will be equivalent when
