Laplace transform
of a different variable p. The Laplace transform 
of f(x) is defined as
The transform is useful in solving differential equations, as it handles derivatives well; for example, the transform of f′(x) equals 
. At its simplest, a differential equation in f(x) is transformed into an algebraic equation involving 
which is solved to find 
; by recognizing 
as the transform of a function, or by applying an inverse transform theorem, the solution f(x) can then be found. For a list of Laplace transforms, see appendix 10. See also Fourier transform.
