# Are the two polar coordinates the same: (8, pi/3), (-8, -pi/3)?

Jan 14, 2016

No.

#### Explanation:

$\frac{\pi}{3}$ and $- \frac{\pi}{3}$ are separated by only $\frac{\pi}{3} - \frac{- \pi}{3} = \frac{2 \pi}{3}$ which

is only ${120}^{o}$

If they were the SAME coordinate, they must be separated by exactly ${180}^{o}$ or $\pi$.

hope that helped
