Second order differential equation solution

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.

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.

What is general solution to a differential equation?

General Solution of a Differential Equation A General Solution of an nth order differential equation is one that involves n necessary arbitrary constants. Similarly, the general solution of a second order differential equation will contain 2 necessary arbitrary constants and so on.

How do you solve second order nonhomogeneous differential equations?

To solve a nonhomogeneous linear second-order differential equation, first find the general solution to the complementary equation, then find a particular solution to the nonhomogeneous equation.

How do you solve a linear equation that is homogeneous?

Use Gaussian elimination to solve the following homogeneous system of equations.Solution: By elementary transformations, the coefficient matrix can be reduced to the row echelon form.Solution check: Show that the set of values of the unknowns.Solution: Transform the coefficient matrix to the row echelon form:

What is a coupled differential equation?

Coupled Differential Equations Typically a complex system will have several differential equations. The equations are said to be “coupled” if output variables (e.g., position or voltage) appear in more than one equation. Two examples follow, one of a mechanical system, and one of an electrical system.

What is homogeneous equation in differential equation?

A first order differential equation is said to be homogeneous if it may be written. where f and g are homogeneous functions of the same degree of x and y. In this case, the change of variable y = ux leads to an equation of the form. which is easy to solve by integration of the two members.

Can a differential equation have more than one solution?

As we will see eventually, it is possible for a differential equation to have more than one solution. We would like to know how many solutions there will be for a given differential equation. If we solve the differential equation and end up with two (or more) completely separate solutions we will have problems.

How do you solve a differential equation with two variables?

Step 1 Separate the variables by moving all the y terms to one side of the equation and all the x terms to the other side:Multiply both sides by dx:dy = (1/y) dx. Multiply both sides by y: y dy = dx.Put the integral sign in front:∫ y dy = ∫ dx. Integrate each side: (y2)/2 = x + C.Multiply both sides by 2: y2 = 2(x + C)

Equation for maximum height

What is the formula for height in physics? Determine how high the projectile traveled above its initial height by using the following formula where V is the initial vertical velocity and T is the time it takes to reach its peak: Height = V * T +1/2 * -32.2 ft/s^2 *T^2 For example, if you […]

Potential energy equation physics

What is potential energy physics? To summarize, potential energy is the energy that is stored in an object due to its position relative to some zero position. An object possesses gravitational potential energy if it is positioned at a height above (or below) the zero height. What is potential and kinetic energy? All forms of […]
