Document Summary
6. 3 trigonometric functions of any angle notes: sterling. Provide a generalization to each of the key terms listed in this section. If denominator = 0 t hen denominator = u ndef ined. What is a coterminal? b c b c = sin . The coterminal occurs when there are two angles that are in standard position if they both have the exact same terminal side. Thanks to the angle, which also means in this case, and the following degrees and radians where k can be expressed as any integer would be coterminal: In radians sin( + 2 k) = sin cos( + 2 k) = cos tan( + 2 k) = tan csc( + 2 k) = csc sec( + 2 k) = sec cot( + 2 k) = cot . Quadrant of sin cos tan csc sec cot . P ositive n egative n egative p ositive n egative n egative.
