Just remember the cosine of an angle is the side adjacent to the angle divided by the hypotenuse of the triangle. In the diagram, the adjacent side is a and the hypotenuse is c , so cosθ=ac . To find θ , you use the arccos function , which has the same relationship to cosine as arcsin has to sine. 18 Sept 2016
