Solve cos3x+cosx-cos2x=0

Solve: cos3x+cosx-cos2x=0

Solve: cos3x+cosx-cos2x=0

Find the general solution of the following equations : cos3x+cosx-cos2x=0

Solve the following trigonometric equation : cos 3x + cosx -cos 2x = 0 .

Find the general solution of the following equations: cos 3x + cosx- cos 2x = 0

cosx + cos2x + cos3x=0

Solve cosx+cos3x-2cos2x=0

Statement-I: x inQ_(1) and cosx+cos3x=cos2x then x=30^(@)or45^(@) Statement-II: x in(0,2pi) and Cosecx+2=0 then x=(7pi)/(6),(11pi)/(6) Statement-III: x in[0,2pi] and (2cosx-1)(3+2cosx)=0 then x=(pi)/(3),(5pi)/(3) wich of the above statements is correct?
