Determine the exact values of the six trigonometric functions of the angle .
| sin() | = | |
| cos()= | ||
| tan() | = | |
| csc() | = | |
| sec() | = | |
| cot() | = |
Solution
tan theta=y/x=-60/-32=15/8
cot theta=1/tan theta=8/15
Here oppsite=15 , adjacent=8
hypotenuse=sqrt(64+225)=17
sin theta=opposite/hypotenuse=-15/17
cos theta=adjacent/hypotenuse=-8/17
csc theta=1/sin theta=-17/15
sec theta=1/cos theta=-17/8
