About LinkBacksHi,
The three sides of the triangle being a, b and c.
1. Can anyone get me the derivation of the law of cosine.
2. Also, the law of sine.
where,
A, B and C are the internal angles subtended by the sides of the triangle a, b and c respectively.

You'll find six proofs of the cosine rule here, and a discussion of the sine rule here.Originally Posted by willki
