solve using identities for all angles (dont use multiple angle method)show work please cuz i am so confused.
2sin2x-3sinx=0

1. 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,...
