Unformatted text preview: DeFnition sine A sin A = opposite side hypotenuse = a c cosine A cos A = adjacent side hypotenuse = b c tangent A tan A = opposite side adjacent side = a b cosecant A csc A = hypotenuse opposite side = c a secant A sec A = hypotenuse adjacent side = c b cotangent A cot A = adjacent side opposite side = b a We will usually use the abbreviated names o± the ±unctions. Notice ±rom Table 1.2 that the pairs sin A and csc A , cos A and sec A , and tan A and cot A are reciprocals: csc A = 1 sin A sec A = 1 cos A cot A = 1 tan A sin A = 1 csc A cos A = 1 sec A tan A = 1 cot A...
