solve using identities for all angles (dont use multiple angle method)show work please cuz i am so confused.
2sin2x3sinx=0

Steve
dunno what you mean by "dont use multiple angle method" since
sin2x = 2 sinx cosx
4sinx cosx  3sinx = 0
sinx(4cosx  3) = 0
sinx = 0, so x = 0,180,360,...
cosx = 3/4, so x = 41.4,318.6,...
