Once you know b and c, you can find a by the Pythagorean theorem. 33. You know b and cos B. Unfortunately, cos B is the ratio of the two sides you don’t know, namely, a/c. Still, this gives you an equation to work with: 1/3 = a/c. Then c = 3a. The name cosine comes from the Latin prefix co-and sine function – so it literally means sine complement. And, indeed, the cosine function may be defined that way: as the sine of the complementary angle – the other non-right angle. The abbreviation of cosine is cos, e.g., cos(30°).
