You can put this solution on YOUR website! Solve the multiple-angle equation. (Enter your answers as a comma-separated list. Use n as an integer constant. Enter your response in radians.)
sec 3x − 2 = 0
-----
Note:: Since sec(3x) = 2, cos(3x) = 1/2
arccos(1/2) = 3x = pi/3 or 3x = -pi/3
----------------------------------------
x = pi/8 or x = -pi/9
