The smallest positive values of x and y which satisfy tan(x-y) =1, sec(x+y) = 2/√3 are
If x is an acute angle and sin(x+280) =cos (3x-780), then x=
If cos θ=cos 5π/4, then θ=
All the values of x satisfying sin 2x+ sin 4x= 2 sin 3x are
If cos θ+√3 sinθ=2 then θ=
If cot θ+ cosec θ= √3 then θ=
If 2 Sin2x + √3 Cosx+1=0, then θ=
