Linearity of Differential Equations
Linear differential equations are equations in which the dependent variable and its derivatives appear in a linear manner. Non-linear differential equations involve products or powers of the dependent variable and its derivatives.
Degree of Differential Equations
The degree of a differential equation is the highest power of the highest-order derivative present in the equation. For example, a first-degree differential equation has the highest derivative raised to the power of 1.
Analysis of the Given Equation
The given differential equation is:
d^2y/dx^2 +x^2 dy/dx +x^3 y=e^x
1. The highest derivative present is the second derivative, making it a second-degree differential equation.
2. The terms involving y and its derivatives are linear (1st degree) since they do not involve products or powers of y or its derivatives.
3. The presence of x^2 dy/dx and x^3 y terms does not affect the linearity of the equation since they are multiplied by y or its derivative.
Conclusion
The given differential equation is a linear differential equation of second degree. It is not non-linear as it does not involve products or powers of y or its derivatives. The linearity and degree of the equation are crucial in determining the methods and techniques used to solve it.
