The polar co-ordinates of P are `(2,(pi)/(6))`. If Q is the image of P about the X-axis then the polar co-ordinates of Q are . . . .

A

`(2,(5pi)/(6))`

B

`(2,(pi)/(6))`

C

`(2,(pi)/(3))`

D

`(2,(11pi)/(6))`

Text Solution

Verified by Experts

The correct Answer is:
D
We have, polar coordinates of P are `(2,(pi)/(6))` if Q is the image of P about the X-axis
`thereforeQ-=(2,-(pi)/(6))`
`impliesQ-=(2,(11pi)/(6))`
