WebA first order differential equation is said to be linear if it can be written as. y ′ + p(x)y = f(x). A first order differential equation that cannot be written like this is nonlinear. We say that Equation 2.1.1 is homogeneous if f ≡ 0; otherwise it is nonhomogeneous. WebIn this work, we present a new technique for the oscillatory properties of solutions of higher-order differential equations. We set new sufficient criteria for oscillation via comparison with higher-order differential inequalities. Moreover, we use the comparison with first-order differential equations. Finally, we provide an example to illustrate the importance of the …
