Question

use the given values to evaluate (if possible) all six trigonometric functions.

Answer 1

Step 1:

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.

So lies in quadrant III.

Definition of trigonometric function :

.

.

Opposite side = 8, adjacent side = 15 and hypotenuse = 17.

Tangent and Cotangent functions are positive and remaining trigonometric functions are negative.

Where, lies in quadrant III.
