Precalc coterminal with given angle

Question

Find an angle between 0 and 2𝜋 that is coterminal with the given angle.

-5 𝜋/3 in fraction form

Answer 1

-5pi/3 + 2pin where n = any integer will be an angle coterminal with -5pi/3

or -5pi/3= -5pi/3 x 180/pi = -300 degrees

...-300, 60, 420, 780, ... degrees. an infinite number of angles are coterminal with -5pi/3

Answer 2

(-5π / 3) + (2π / 1) = ?
