Multiple Choice

Use the given values to evaluate (if possible) three trigonometric functions cos x, sin x, tan x.
$\sec x = 4 , \sin x > 0$

A) $\begin{array} { l } \cos x = \frac { 1 } { 4 } \\\sin x = - \frac { \sqrt { 15 } } { 4 } \\\tan x = \sqrt { 15 }\end{array}$
B) $\begin{array} { l } \cos x = \frac { 1 } { 4 } \\\sin x = \frac { \sqrt { 15 } } { 4 } \\\tan x = \sqrt { 15 }\end{array}$
C) $\begin{array} { l } \cos x = \frac { 1 } { 4 } \\\sin x = - \frac { \sqrt { 15 } } { 4 } \\\tan x = - \sqrt { 15 }\end{array}$
D) $\begin{array} { l } \cos x = - \frac { 1 } { 4 } \\\sin x = \frac { \sqrt { 15 } } { 4 } \\\tan x = \sqrt { 15 }\end{array}$
E) $\begin{array} { l } \cos x = - \frac { 1 } { 4 } \\\sin x = - \frac { \sqrt { 15 } } { 4 } \\\tan x = - \sqrt { 15 }\end{array}$
