正弦定理与余弦定理都揭示了三角形边角之间内在本质的联系.尽管形式不同,但实质相同.本文从三个方面探讨它们的统一性.一、正弦定理与余弦定理的统一证明
Sinusoidal and cosine theorems reveal the intrinsic relationship between the triangular corners, though they are different in form, but they are essentially the same.This paper discusses their unity from three aspects: 1. The unified proof of the sine and cosine theorems
