Show transcribed image text Using the method of separation of variables, find the general solution of the partial differential equation You do NOT need to determine the constants in the solution.... As for the wave equation, we take the most general solution by adding together all the possible solutions, satisfying the boundary conditions, to obtain (2.58) The final step is to apply the initial conditions, namely

where $\,f(x)\,$ is a function of $\,x\,$ alone and $\,f(y)\,$ is a function of $\,y\,$ alone, equation (1) is called variables separable. To find the general solution of equation (1), simply equate the integral of equation (2) to a constant $\,c\,$.... The method of separation of variables can also be applied to some equations with variable coefficients, such as f xx + x 2 f y = 0, and to higher-order equations and equations involving more variables.

Seven steps of the approach of separation of Variables: 1) Separate the variables: 2) Find the ODE for each “variable”. 3) Determine homogenous boundary values to stet up a Sturm- Liouville problem. 4) Find the eigenvalues and eigenfunctions. 5) Solve the ODE for the other variables for all diﬀerent eigenvalues. 6) Superpose the obtained solutions 7) Determine the constants to how to find an underground spring on your property Outline ofthe Methodof Separation of Variables We are going to solve this problem using the same three steps that we used in solving the wave equation. Step 1 In the ﬁrst step, we ﬁnd all solutions of (1) that are of the special form u(x,t) = X(x)T(t) for

## How To Find General Solution Separation Of Variables

This implies that the method of separation of variables is of quite general applicability. Finally, as a simple example of the solution of Poisson's equation in spherical geometry, let us consider the case of a conducting sphere of radius , centered on the origin, placed in a uniform …

- the general solution of the homogeneous equation (1.9), and add to this a particular solution of the inhomogeneous equation (check that the di erence of any two solutions of the inhomogeneous equation
- This solution is easy enough to get an explicit solution, however before getting that it is usually easier to find the value of the constant at this point. So apply the initial condition and find the value of \(c\).
