The trigonometric functions are and
.
The value of tangent function is positive in quadrant I and III.
\The value of secant function is negative in quadrant II and III.
\Thus, the angle lies in quadrant III.
From the definition of trigonometric function :
\.
.
,
, and
.
Since lies in quadrant III, tangent and cotangent functions are positive and remaining trigonometric functions are negative.
