t = 

11π

6

 

P(x, y) = 

 

Answer 1

Step 1:

The value of is .

Find the reference number .

The reference number associated with is the shortest distance along the unit circle between the terminal points determined by and -axis.

Reference number is

Step 2:

Find the terminal number.

The point obtained by moving along the unit circle in either clockwise or anti clockwise direction is the terminal distance.

The reference number is , the terminal point is .

Since lies in fourth quadrant, both .

Terminal point is .

Solution:

Terminal point is .
