Best ResponseYou've already chosen the best response.2it asks for values in the interval 0 to 2pi and the sine can be negative or positive so there is an angle in each quadrant which satisfies the equation.

Best ResponseYou've already chosen the best response.0This one is solving on the same interval cos(3x) = 1 > 3x = arccos(1)  >3x=pi So x= pi/3

Best ResponseYou've already chosen the best response.2so x = pi/3 , pi, 5pi/3 all of which are in the interval 1 to 2pi

Best ResponseYou've already chosen the best response.2if x must be in the interval 0 to 2pi then 3x is in interval 0 to 6pi
