Aug 9, 2015 Find cos2( π 3) Ans: 1 4 Explanation: Use the trig identity: cos2a = 2cos2a − 1. cos( 2π 3) = − 1 2 = 2cos2( π 3) − 1 2cos2( π 3) = 1 − 1 2 = 1 2 cos2(π 3) = 1 4The Law of Cosines is useful for finding: the third side of a triangle when we know two sides and the angle between them (like the example above) the angles of a triangle when we know all three sides (as in the following example) Example: What is Angle "C" ...? The side of length "8" is opposite angle C, so it is side c.
