Methods of separation
Assuming that the wave function ( ) is separable, i.e. assuming the function of two variables can be written as the product of two different functions of a single variable:
then, using standard mathematical techniques of Partial Differential equations, it can be shown that the wave equation can be rewritten as two distinct differential equations given by:
and
where the first equation is solely dependent on time , and the second equation depends only on position , and where is just a number. Generalizations can easily be made for higher numbers of spacial dimensions (up till dimensions of space and of time).

- Why has KA not roll out a typesetting system such as LaTeX in comment section yet? We users surely need something to express math functions.(2 votes)
