## What is second order ordinary differential equation?

An ordinary differential equation of the form. (1) Such an equation has singularities for finite under the following conditions: (a) If either or diverges as , but and remain finite as , then is called a regular or nonessential singular point. (

## Why does a second order differential equation have two solutions?

5 Answers. second order linear differential equation needs two linearly independent solutions so that it has a solution for any initial condition, say, y(0)=a,y′(0)=b for arbitrary a,b. from a mechanical point of view the position and the velocity can be prescribed independently.

## Can a second order differential equation have more than two solutions?

A second order differential equation may have no solutions, a unique solution, or infinitely many solutions.

## How many solutions does a second order differential equation have?

To construct the general solution for a second order equation we do need two independent solutions.

## How many solutions do you need in a fundamental set of solutions for a second order differential equation?

Two solutions are “nice enough” if they are a fundamental set of solutions.

## What is the fundamental solution of a differential equation?

In mathematics, a fundamental solution for a linear partial differential operator L is a formulation in the language of distribution theory of the older idea of a Green’s function (although unlike Green’s functions, fundamental solutions do not address boundary conditions).

## How do you solve a separable variable?

Follow the five-step method of separation of variables.

1. In this example, f(x)=2x+3 and g(y)=y2−4.
2. Divide both sides of the equation by y2−4 and multiply by dx.
3. Next integrate both sides:
4. It is possible to solve this equation for y.
5. To determine the value of C3, substitute x=0 and y=−1 into the general solution.
