Answer:
The correct option is B.
Step-by-step explanation:
If polar coordinates of point P are
[tex]P=(r,\theta)[/tex]
Where, r is real number and θ is in radian, then all polar coordinates of point P are defined as
[tex]P=(r,\theta+2n\pi)[/tex]
[tex]P=(-r,\theta+(2n+1)\pi)[/tex]
The given coordinates are [tex]P(5,-\frac{\pi}{6})[/tex]. So, all polar coordinates of point P are
[tex]P=(5,-\frac{\pi}{6}+2n\pi)[/tex]
[tex]P=(-5,-\frac{\pi}{6}+(2n+1)\pi)[/tex]
Therefore correct option is B.
