, we have
:
or 
.
, or every odd multiple of 
. We denote this by 
for 
(
is any integer).
, or every even multiple of 
. We write this as 
for 
. In that case, you'd have only 3 solutions, 
.
, because that makes the left hand side of the original equation undefined. So the general solution is actually 
(all non-zero integers).
