Question 38

Multiple Choice

Use the given function value(s) ,and trigonometric identities (including the cofunction identities) ,to find the indicated trigonometric functions. ?? cot⁡α=3\cot \alpha = 3 ? tan⁡α and cot⁡(90∘−α) \tan \alpha \text { and } \cot \left( 90 ^ { \circ } - \alpha \right) ?


A) ? tan⁡α=−13\tan \alpha = - \frac { 1 } { 3 } and cot⁡(90∘−α) =−13\cot \left( 90 ^ { \circ } - \alpha \right) = - \frac { 1 } { 3 }
B) ? tan⁡α=13\tan \alpha = \frac { 1 } { 3 } and cot⁡(90∘−α) =3\cot \left( 90 ^ { \circ } - \alpha \right) = 3
C) tan⁡α=13\tan \alpha = \frac { 1 } { 3 } and cot⁡(90∘−α) =13\cot \left( 90 ^ { \circ } - \alpha \right) = \frac { 1 } { 3 }
D) ? tan⁡α=3\tan \alpha = 3 and cot⁡(90∘−α) =3\cot \left( 90 ^ { \circ } - \alpha \right) = 3
E) ? tan⁡α=3\tan \alpha = 3 and cot⁡(90∘−α) =13\cot \left( 90 ^ { \circ } - \alpha \right) = \frac { 1 } { 3 }
