What angles are coterminal to an angle measuring −5π/3 or 8π/7?

 What angles are coterminal to an angle measuring −5π/3 or 8π/7?

Hello ocmac!

Two angles are "coterminal" if they differ by an integral multiple of 360 °.

Zwei Winkel sind "coterminal", wenn sie sich um ein ganzzahliges Vielfaches von  360°  unterscheiden.

\(\frac{2\pi}{-\frac{5\pi}{3}}=\color{red}-\frac{6}{5}\)    \(The\ angle\ is\ not\ coterminal\ to\ 2\pi.\)

\(\frac{2\pi}{\frac{8\pi}{7}}=\color{red}-\frac{7}{4}\)        \(The\ angle\ is\ not\ coterminal\ to\ 2\pi.\)
