Question

how do i find the coordinates and angle measure of 11pi/3?

Answer 1

Look at the unit circle:

See attached and decide :D (Look for 11*pi/3)

Answer 2

11pi/3 is not on the unit circle

Answer 3

Oh, I'm sorry, I read that as 11pi/6

Anyhow:

For the x coordinate: Do: cos 11pi/6
Y coordinate is: sin 11pi/6

And to find the angle:

Do: 11pi/6 * (180/pi)

Answer 4

Oops, make it:

For the x coordinate: Do: cos 11pi/3
Y coordinate is: sin 11pi/3

And to find the angle:

Do: 11pi/3 * (180/pi)
