Question

What does coterminal mean

anonymous · Answer

Isn't it when you add or subtract 360 degrees?

anonymous · Answer

no f7cking idea m8

directrix · Answer

Two I am thinking of are these: (1)    pi/5 + 2 pi = pi/5 + 10 pi / 5 = (11 pi )/ 5

and (2)   pi/5 - 2 pi = ?

anonymous · Answer

how did you get pi/5 + 10 pi/5?

directrix · Answer

10 pi/5 = 2 pi. Every 360 degrees (2 pi), the angles are coterminal. Consider an angle of 30 degrees on the unit circle. Add 360 degree and the angle 390 degrees will have a side terminal with the 30 degree angle.
