In particular we will define a linear operator, a linear partial differential equation and a homogeneous partial differential equation. We seek a solution to the pde (1) (see eq.(12)) in the form u(x,z)=x(x)z(z) (19) substitution of (19) into (12) gives:

The method of separation of variables relies upon the assumption that a function of the form, u(x,t) = φ(x)g(t) (1) (1) u ( x, t) = φ ( x) g ( t) will be a solution to a linear homogeneous partial differential equation in x x and t t. This separation leads to ordinary differential equations that are solved (a) by using the “first separation” followed by integration, (b) by utilizing “ept ” or “epx ” substitution method for.

We Seek A Solution To The Pde (1) (See Eq.(12)) In The Form U(X,Z)=X(X)Z(Z) (19) Substitution Of (19) Into (12) Gives:

The method of separation of variables is also used to solve a wide range of linear partial differential equations with boundary and initial conditions, such as the heat equation, wave equation, laplace equation, helmholtz equation and biharmonic equation. One important requirement for separation of variables to work is that the governing partial differential equation and initial and boundary conditions be linear. We also give a quick reminder of the principle of superposition.
