Document Summary
Objective 1: understanding the right triangle definitions of the trigonometric functions. The right triangle definition of the trigonometric functions. 1: if is an acute angle and if sec. , then find the exact values of the remaining trigonometric functions of . sin = __________ cos = _________ _ cot = __________ csc = ___________ tan = ___________ You must memorize these two triangles so you can find the exact value of any trig function of one of these special angles!! 2: use the special triangles to find the exact value of 3 sin. The quotient identities tan sin cos cot cos sin. 3: find the exact value of each of the following using identities. Two positive angles are said to be complementary if the sum of their measures is. The acute angles of every right triangle are complementary. Cofunction identities sin cos tan cot sec csc. 4: find a cofunction equivalent to cot 35 .
