Solve the multiple-angle equation. (Enter your answers as a comma-separated list. Use n as an integer constant. Enter your response in radians.) 2 cos x/3 2 = 0
Solution
2cos(x/3) - sqrt2 =0
cos(x/3) = sqrt(2)/2
x/3 = cos^-1[sqrt(2)/2]
x/3 = 2k*pi +pi/4
x/3 = ( 8k*pi +pi)/4
x = ( 24k*pi +3pi)/4
x/3 = 2pi - pi/4 = 7pi/4
x/3 = 2k*pi +7pi/4
= (8k*pi +7pi)/4
x= ( 24k*pi +21pi)/4
Solution : x = = ( 24n*pi +3pi)/4 , ( 24n*pi +21pi)/4
