I tend to convert radians to degrees so I can
visualize the angle.
+pi%2F3+%7B%7B%7B+radians+=+%7B%7B%7B+180%2F3+ degrees
+pi%2F3+ radians = +60+ degrees
----------------------------------
+pi%2F2+ radians = +180%2F2+ degrees
+pi%2F2+ radians = +90+ degrees
---------------------------------
(1)
I'll do the conversions to degrees:
+cos%28+60+%29+%2B+sin%28+90+%29+
+1%2F2+%2B+1+=+3%2F2+
(2)
+4%2Acos%28+60+%29+%2B+3%2Atan%28+60+%29+
+4%2A%281%2F2%29+%2B+3%2A%28+sqrt%283%29%2F1+%29+
+2+%2B+3%2Asqrt%283%29+
