cos b In like manner , sin B cos A = cos a 139 From , , and , we have cos c = cos a cos b = cos A cos B X cot A cot B sin B sin A
Prove the identity: sin x = cos^2 x cos sin cos b In like manner , sin B cos A = cos a 139 From , , and , we have cos c = cos a cos b = cos A cos B X cot A cot B sin B sin A cos 60 ¥ม Page 2 We will usually use the abbreviated names of the functions Notice from Table that the pairs sin A and cosec A , cos A and sec A, and tan
