Best ResponseYou've already chosen the best response.3sin(2x) + sin(4x) = 0 sin(2x) + 2sin(2x)cos(2x) = 0 sin(2x)[1 + 2cos(2x)] = 0 sin(2x) = 0 or 2cos(2x) = 1 > cos(2x) = 1/2 when sin(2x) = 0 2x = 0, pi, 2pi, 3pi x = 0, pi/2, pi, 3pi/2 when cos(2x) = 1/2 2x = 2pi/3, 4pi/3, 8pi/3, 10pi/3 x = pi/3, 2pi/3, 4pi/3, 5pi/3 so x = 0, pi/2, pi, 3pi/2 , pi/3, 2pi/3, 4pi/3, 5pi/3 @jim_thompson5910 is thsi correct?
