The relationship explains the plural "s" in Law of Sines : there are 3 sines after all. Another important relationship between the side lengths and the angles of a triangle is expressed by the Law of Cosines. Why do we use the plural "s" in the Law of Cosines? The expression itself involves a single cosine , but by rotation or, as A.

Einstein might have said, by symmetry similar formulas are valid for other angles:. In fact, I do not know the exact sources of the existing nomenclature.

But there is another plurality involved with the Law of Cosines. Most of the proofs of the Law consider separately the cases of acute, right, and obtuse triangles. Here's how the former could be translated into plain English [ Euclid , p. In obtuse-angled triangles the square on the side subtending the obtuse angle is greater than the squares on the sides containing the obtuse angle by twice the rectangle contained by one of the sides about the obtuse angle, namely that on which the perpendicular falls, and the straight line cut off outside by the perpendicular towards the obtuse angle.

With the reference to the diagram on the right, Euclid's proof amounts to the following derivation. This is in fact the same proof as we used to show that the law of cosines is a direct consequence of a less general Pythagorean theorem.

I am grateful to Douglas Rogers who suggested the reference to the Elements. Also, the latest formula has a slightly different form discovered by Larry Hoehn that generalizes the Pythagorean theorem in a little different way. The first one uses the power of a point with respect to a circle theorem, the other the theorem of Ptolemy.

The first proof assumes that C is acute, the second that it's obtuse. See if you can modify the diagrams to account for the remaining cases. In Trigonometric Delights [ p. Maor remarks that it would be entirely appropriate to call the latter identity the Law of Cosines because it does contain 2 cosines with an immediate justification for the plural "s".

However, these do not seem to work for acute angles C. The proofs generalize that of the Pythagorean theorem by K. This applet requires Sun's Java VM 2 which your browser may perceive as a popup.
