Step 1:

\

The trigonometric function is $\"\"$ and $\"\"$ .

\

$\"\"$ is positive and $\"\"$ is negative means $\"\"$ lies in fourth quadrant .

\

In fourth quadrant all trigonometric functions are negative, except $\"\"$ and $\"\"$ .

\

Pythagorean identities is $\"\"$ .

\

Substitute $\"\"$ in above formula.

\

$\"\"$

\

Since $\"\"$ , $\"\"$ .

\

Step 2:

\

Recall the reciprocal identity: $\"\"$

\

Substitute $\"\"$ in above formula.

\

$\"\"$ .

\

Pythagorean identity is $\"\"$

\

Substitute $\"\"$ in above formula.

\

$\"\"$

\

$\"\"$ in fourth quadrant , $\"\"$ .

\

Solution:

\

$\"\"$ and $\"\"$ .
