I'm curious why you would go to the trouble of transforming your original DE when you can solve it directly. It's just a constant coefficient DE with a non-homogeneous polynomial term.

it was y'+by^2=cx^m ,Iforgot to type the y squared power

Here is what Maple gives, for what it's worth:

1. What is the Bessel solution to differential equations?

The Bessel solution to differential equations is a set of solutions to a particular type of differential equation known as the Bessel equation. These solutions involve the use of Bessel functions, which are special mathematical functions that arise in many areas of physics and engineering.

2. When is the Bessel solution used?

The Bessel solution is commonly used in problems involving cylindrical or spherical symmetry, such as in heat transfer, fluid dynamics, and electromagnetic wave propagation. It is particularly useful when dealing with problems that have circular or spherical boundaries.

3. How is the Bessel solution different from other methods of solving differential equations?

The Bessel solution differs from other methods of solving differential equations in that it involves the use of special functions, rather than algebraic or trigonometric functions. Bessel functions have unique properties that make them well-suited for solving certain types of equations.

4. What are the applications of the Bessel solution?

The Bessel solution has a wide range of applications in physics and engineering. It is commonly used in problems involving heat transfer, acoustics, electromagnetic waves, and fluid mechanics. It is also used in the solution of boundary value problems, eigenvalue problems, and other types of differential equations.

5. Can the Bessel solution be used for any type of differential equation?

No, the Bessel solution is only applicable to a specific type of differential equation known as the Bessel equation. It cannot be used to solve other types of differential equations, such as ordinary differential equations or partial differential equations.
