To find the exact values of the trigonometric functions for the angle
with a point
on its terminal side, we can use the following steps:1. Find the radius (hypotenuse) of the right triangle formed by the point
and the origin
. - The radius can be found using the Pythagorean theorem:
.2. Find the cosine of
. - The cosine of
is the ratio of the adjacent side to the hypotenuse:
.3. Find the cosecant of
. - The cosecant of
is the reciprocal of the sine of
:
. - The sine of
is the ratio of the opposite side to the hypotenuse:
. - Therefore,
.4. Find the tangent of
. - The tangent of
is the ratio of the opposite side to the adjacent side:
.In summary, the exact values of the trigonometric functions for the angle
with a point
on its terminal side are:-
-
- $\tan\Theta = \frac{3
