Use the given function values and trigonometric identities i

Use the given function value(s), and trigonometric identities (including the cofunction identities), to indicated trigonometric functions. cot alpha = 3 tan alpha = -1/3 and cot(90 degree - alpha) = -1/3 b. tan alpha = 1/3 and cot(90 degree - alpha) = 3 c. tan alpha = 1/3 and cot(90 degree - alpha) = 1/3 d. tan alpha = 3 and cot (90 degree - alpha) = 3 e. tan alpha = 3 and cot(90 degree - alpha) = 1/3

Solution

given cot =3

identity tan =1_/cot

=>tan =1_/3

cot(90^o-) =tan , since cot and tan are cofunctions

=> cot(90^o-) =1_/3
