y = sinx.sin(120-x).sin(120 + x)
Period of y = LCM of period of sinx , sin(120-x) and sin(120 + x)
Period of sinx = 2π
Period of sin(120 - x) = 2π
Period of sin(120+ x) = 2π
So, period of y = LCM { 2π, 2π, 2π }
Period of y = 2π
Period of y = LCM of period of sinx , sin(120-x) and sin(120 + x)
Period of sinx = 2π
Period of sin(120 - x) = 2π
Period of sin(120+ x) = 2π
So, period of y = LCM { 2π, 2π, 2π }
Period of y = 2π
