Differential Equations

Question:

Test that the nature differential equation x (dy/dx) - y + xsin (y/x) =0 is-

Options:

Homogeneous

Non- homogeneous

May or may not be homogeneous

None of these

Correct Answer:

Homogeneous

Explanation:

The given differential equation is x (dy/dx) - y + xsin (y/x) =0

⇒ dy/dx = {y - xsin (y/x)}/x

Let F(x,y) = {y - xsin (y/x)}/x

⇒ F(tx,ty) = {ty - txsin (ty/tx)}/tx

⇒ F(tx,ty) = t0. F(x,y) 

So, given differential equation is homogeneous differential equation.
