Which quadrant does the given angle 621 degrees lie?
If I remember correctly, this was my way of finding the Q of any
Let q = int (
If q is even and a multiple of 4,
If q is odd and the remainder in ( q/4 ) is 1,
Here, int ( 621/90 ) = 6 that is even but not a multiple of 4.
For that matter, int ( 711/90 )= 7 that is odd but not a multiple of 3. So,
Int ( 801/80 )= 8 that is even but a multiple of 4. So,
Int (891/80)= 9 that is odd but a multiple of 3. So,
