The reason is that using the cosine function eliminates any ambiguity: if the cosine is positive then the angle is acute, and if the cosine is negative then the angle is obtuse. This is in contrast to using the sine function; as we saw in Section 2.1, both an acute angle and its obtuse supplement have the same positive sine.

Pre-Calculus Project: Application of Law of Sines and Law of Cosines A surveyor on one side of a river wants to find the distance between points A and B on the opposite side of the river. On her side, she chooses points C and D, which are 20 meters apart, and measures the angles as shown in the figure below.We start off with our original equation of . Since c is the hypotenuse of this right triangle, then angle C is opposite side c and is equal to 90 degrees. If angle C is equal to 90 degrees, then cos (C) = cos (90) = 0. This makes 2*a*b*cos (C) equal to 0. The equation becomes which is exactly the Pythagorean formula.
