Second order non homogeneous ODE, IVP

In summary, the conversation is discussing how to solve the equation x^2y''-4xy'+6y=x^3, with initial conditions of x>0, y(1)=3, and y'(1)=9. The suggested solution is y=x^2+2x^3+x^3lnx, but the person is unsure if they solved it correctly and is asking for feedback. The conversation also mentions using both Euler Cauchy and variation of parameters methods to find a particular solution. A link is provided for further explanation on how to construct a particular solution.

I know that the answer is: y=x^2+2x^3+x^3lnx
Where did I go wrong. I was wondering if it's even logical to solve it as an Euler Cauchy and then use variation of parameters...

What is a second order non homogeneous ODE?

A second order non homogeneous ODE (ordinary differential equation) is a mathematical equation that describes how a function changes over time, taking into account both the function itself and its rate of change. It is considered non homogeneous when the right side of the equation includes a function that is not equal to zero.

What is an initial value problem (IVP)?

An initial value problem (IVP) is a type of differential equation that includes conditions for the function at a specific starting point. This starting point, or initial value, is usually given as a specific value for the function and its derivative at a certain time or position.

How do you solve a second order non homogeneous ODE with an IVP?

To solve a second order non homogeneous ODE with an IVP, you will need to use a variety of techniques such as substitution, integration, and solving for constants. This process can be complex and may require knowledge of advanced mathematical concepts.

What is the difference between a homogeneous and non homogeneous ODE?

The main difference between a homogeneous and non homogeneous ODE is that a homogeneous ODE does not include any functions on the right side of the equation, whereas a non homogeneous ODE does. This means that the solution to a homogeneous ODE will only involve constants, while the solution to a non homogeneous ODE will also involve a function.

Why are initial conditions important in solving a second order non homogeneous ODE with an IVP?

Initial conditions are important in solving a second order non homogeneous ODE with an IVP because they provide specific starting points for the function and its derivative. These conditions help to determine the values of constants in the solution and provide a unique solution to the equation.
