If It could be that or (for angles and ).

could also be any other angle differing from those by a multiple of .
Starting from = ,
or from =
a way of expressing all those angle with one formula is
for any integer .
So ---> for any integer .
That gives you infinite pairs of co-terminal angles:
For we have and .
For we have and .
For we have and .
For we have and .
There are infinitely more pairs.
