� Variable separable method is used to solve such an equation in which variables
can be separated completely i e terms containing y should remain with dy
and terms containing x should remain with dx � A differential equation which can be expressed in the form
( , ) or
( , )
dy
dx
f x y
g x y
dx
dy
 
 
where, f (x, y) and g(x, y) are homogenous
functions of degree zero is called a homogeneous differential equation
