<PRE><B>Question 1030060</B>
Start at 0 degrees and turn the unit vector
360 degrees at a time counter clockwise
-------------------
After a 360 degree turn,
{{{ 632 - 360 = 272 }}} degrees are left
and the unit vector is back at 0 degrees
-------------------
Now turn the unit vector 270 degrees, ( going counter clockwise)
which is 90 degrees past 180 degree location
and 2 degrees are left, which will
put you in the 4th quadrant
--------------------
If you do any trig functions of this angle, 
the angle will be {{{ 90 - 2 = 88 }}} degrees
to the 0 degree location in the 4th quadrant
--------------------
Some trig functions are negative in the 4th quadrant,
cos( 272 ) = (+) cos( 88 )
sin( 272 ) = (-) sin( 88 )
--------------------
hope this helps
