Question

the angle between 0 and$2\pi \: in \: radians \: that \: \\ is \: coterminal \: with \: the \: \\ angle \: \frac{87\pi}{7} \: radians \: is$

Answer 1

Explanation :

• To get coterminal angles you simply have to add or subtract 2 pi .

,

• In this instance, we are looking for a coterminal angle between 0 and 2pi.

,

• therefore we will add / subtract 2pi to 87pi /7 :

-2pi + (87 pi /7) = -(14 pi /7) + (87pi /7)

= 73pi /7
