Question 45

Multiple Choice

Use the given values to evaluate (if possible) three trigonometric functions cotθ,secθ,cosθ\cot \theta , \sec \theta , \cos \theta .​ tanθ=4,cosθ<0\tan \theta = 4 , \cos \theta < 0


A) ​ cotθ=14secθ=17cosθ=1717\begin{aligned}\cot \theta & = \frac { 1 } { 4 } \\\sec \theta & = - \sqrt { 17 } \\\cos \theta & = \frac { \sqrt { 17 } } { 17 }\end{aligned}
B) ​ cotθ=4secθ=17cosθ=1717\begin{array} { l } \cot \theta = 4 \\\sec \theta = \sqrt { 17 } \\\cos \theta = \frac { \sqrt { 17 } } { 17 }\end{array}
C) ​ cotθ=14secθ=17cosθ=1717\begin{array} { l } \cot \theta = \frac { 1 } { 4 } \\\sec \theta = - \sqrt { 17 } \\\cos \theta = - \frac { \sqrt { 17 } } { 17 }\end{array}
D) ​ cotθ=14secθ=17cosθ=1717\begin{array} { l } \cot \theta = - \frac { 1 } { 4 } \\\sec \theta = - \sqrt { 17 } \\\cos \theta = - \frac { \sqrt { 17 } } { 17 }\end{array}
E) ​ cotθ=14secθ=17cosθ=1717\begin{array} { l } \cot \theta = \frac { 1 } { 4 } \\\sec \theta = \sqrt { 17 } \\\cos \theta = - \frac { \sqrt { 17 } } { 17 }\end{array}
