If -(pi)/(4) lt x lt (pi)/(4), then the general solution of the differential equation cos^(2)x .(dy)/(dx) - (tan 2x) y = cos^(4)x is

Answer»

`y = (1)/(2) [(TAN 2X + c)/(1-tan^(2)x)]`
`y = (1)/(2) [(cos 2x + c)/(1-tan^(2)x)]`
`y = (1)/(2) [(sin 2x + c)/(1-tan^(2)x)]`
`y = (1)/(2) [(sin x + c)/(1-tan^(2)x)]`
