+5%2A%28pi%2F6%29+=+pi+-+pi%2F6+
This is an angle in the 2nd quadrant that
makes an angle of +pi%2F6+ with horizontal axis
+cos%28+pi%2F6+%29+=+sqrt%283%29%2F2+
+sin%28+pi%2F6+%29+=+1%2F2+
--------------------------
In the 2nd quadrant, the terminal point would be:
( -sqrt(3)/2, 1/2 )
--------------------------
check:
+1%5E2+=+%28+-sqrt%283%29%2F2+%29%5E2+%2B+%281%2F2%29%5E2+
+1+=+.75+%2B+.25+
+1=+1+
OK
