正余弦定理-三角形面积
1.正弦定理:

a b c ? ? ? k ? 2R sin A sin B sin C

R 是 △ ABC 外接圆半径,k 是直径或比值
变形① 变形②

a ? ks i n A , b ? k s i nB ? ,c

k sin C

a b c s i nA ? , s i B n ? , sC in ? k k k a sin A a sin A b sin B ? , ? , ? b sin B c sin C c sin C
a: b: c ? s i nA : s i B n : sC in

变形③

变形④

2. 三角形面积公式: S△ ?

1 1 1 ab sin C ? bc sin A ? ac sin B 2 2 2

?a 2 ? b2 ? c 2 ? 2bc ? cos A ? 3.余弦定理:求边形式 ?b 2 ? a 2 ? c 2 ? 2ac ? cos B ?c 2 ? a 2 ? b2 ? 2ab ? cos C ?

? b2 ? c2 ? a 2 ?cos A ? 2bc ? 2 a ? c2 ? b2 ? 求角形式 ?cos B ? 2ac ? 2 ? a ? b2 ? c2 ?cos C ? 2ab ?

勾股定理是余弦定理的特例

? A 为直角 ? a 2 ? b2 ? c 2
4. 其它需要用的公式

? A 为钝角 ? a 2 ? b2 ? c 2

? A 为锐角 ? a 2 ? b2 ? c 2

?sin( A ? B) ? sin A ? cos B ? cos A ? sin B ?sin( A ? B) ? sin A ? cos B ? cos A ? sin B ? 两角和与差公式 ? ?cos( A ? B) ? cos A ? cos B ? sin A ? sin B ? ?cos( A ? B) ? cos A ? cos B ? sin A ? sin B
cos 2 A ? 2cos2 A ? 1 ? 1 ? 2sin 2 A ,
sin 2 A ?

? ?sin 2 A ? 2sin A ? cos A ? 2 2 ?cos 2 A ? cos A ? sin A ? sin A ? tan A ? cos A ?

1 ? cos 2 A 1 ? cos 2 A 2 , cos A ? 2 2

?A ? B ? C ? ? ?sin( B ? C ) ? sin A ? 三角形内角和公式: ? ?cos( B ? C ) ? ? cos A ? ? tan( B ? C ) ? ? tan A
5. 公式变形的两种转化思想 其一:全部化为边 其二: 全部化为角
