State the type of the differential equation for the equation. xdy – ydx = `sqrt(x^2 + y^2)  "d"x` and solve it

Which of the following is not a homogeneous function of x and y.

F(x, y) = `(sqrt(x^2 + y^2) + y)/x` is a homogeneous function of degree ______.

F(x, y) = `(ycos(y/x) + x)/(xcos(y/x))` is not a homogeneous function.
