The number of solutions of the equation tan 3x = sin 6x in [ 0, Π/6) U ( Π/6,Π/2] is

Question

Vikas TU · Answer

Dear Student,

tan3x = sin 6x => tan3x = 2sin3xcos3x => sin3x/cos3x = 2sin3xcos3x.

Hence one solution is x = 0.

2cos²3x = 1 => cos²3x = 1/2 => cos3x = 1/√2 => x = cos^-1(1/√2)/3 = π/12.

Cheers!!
