In each of the following differential equation show that it is homogeneous and solve it.
(x - y)dy - (x + y)dx = 0
(x - y)dy - (x + y)dx = 0
⇒ the given differential equation is a homogenous equation.
The solution of the given differential equation is :
Put y = vx
Integrating both the sides we get:
Resubstituting the value of y = vx we get
