Solve the following differential equation: `\ cos e c\ xlogy(dy)/(dx)+\ x^2y^2=0`

Text Solution

Verified by Experts

`{cosec} x log y frac{d y}{d x}+x^{2} y^{2}=0`

`Rightarrow {cosec} x log y frac{d y}{d x}=-x^{2} y^{2}`

Separate the variables,

`Rightarrow frac{log (y)}{y^{2}} d y=frac{-x^{2}}{cosecx}} d x`

`Rightarrow int(log y)(frac{1}{y^{2}} d y)=-int x^{2} sin x d x `

`Rightarrow log y(-frac{1}{y})-int(-frac{1}{y^{2}}) d y=x^{2} cos x-int 2 x cos x d x+C `

`Rightarrow-frac{log y}{y}+int y^{-2} d y=x^{2} cos x-2[x sin x-int 1 cdot sin x d x]+C `

`Rightarrow-frac{log y}{y}-y^{-1}=x^{2} cos x-2 x sin x-2 cos x+C`
