Find all polar coordinates of point P where P = ordered pair 4 comma negative pi divided by 3

Hoochie [10]

Answer:

The polar coordinates of point P are $(4,-\frac{\pi}{3}+2n\pi)$ and $(-4,-\frac{\pi}{3}+(2n+1)\pi)$ .

Step-by-step explanation:

The given point is

$P=(4,-\frac{\pi}{3})$

If a point is defined as P(r,θ), then all polar coordinates are

$P(r,\theta)=(r,\theta+2n\pi)$

$P(r,\theta)=(-r,\theta+(2n+1)\pi)$

Where, θ is in radian and n is an integer.

The polar coordinates of point P are

$P(4,-\frac{\pi}{3})=(4,-\frac{\pi}{3}+2n\pi)$

$P(4,-\frac{\pi}{3})=(-4,-\frac{\pi}{3}+(2n+1)\pi)$

Therefore the polar coordinates of point P are $(4,-\frac{\pi}{3}+2n\pi)$ and $(-4,-\frac{\pi}{3}+(2n+1)\pi)$ .
