Step 1:

(1)

Find the point on the unit circle at $\"\"$ .

Since, $\"\"$ is a real number.

Let mark of a distance $\"\"$ along a unit circle, starting point at $\"\"$ and moving in a counterclockwise direction if $\"\"$ is positive or in a clockwise direction if $\"\"$ is negative.

Thus the point is $\"\"$ on the unit circle and it is called as a terminal point.

Hence, $\"\"$ is a counterclockwise direction if $\"\"$ is positive and the terminal point is $\"\"$ .

Graph the unit circle at $\"\"$ .

$\"\"$

Observe the graph:

The unit circle is completed at $\"\"$ terminal point is $\"\"$ .

(2)

Find the point on the unit circle at $\"\"$ .

Since, $\"\"$ is a clockwise direction if $\"\"$ is negative and the terminal point is $\"\"$ .

Graph:

$\"\"$

Observe the graph:

The unit circle is completed at $\"\"$ terminal point is $\"\"$ .

Solution:

At $\"\"$ terminal point is $\"\"$ .
