Definitions of trigonometric functions of any angle :

\

Let $\"\"$ be an angle in standard position with $\"\"$ a point on the terminal side of $\"\"$ and $\"\"$ , then

\

$\"image\"$

\

$\"\"$

$\"\"$

\

The line equation is $\"\"$ .

\

In second quadrant $\"\"$ and $\"\"$ .

\

Consider $\"\"$ , then

\

$\"\"$

\

The point on the line is $\"\"$ .

\

\

Thus, the obtained values are $\"\"$ , $\"\"$ and $\"\"$ .
