Laplace Transform
Laplace Transform
The Laplace transform is used to solve
linear constant coefficient differential
equations. This is achieved by
transforming them to algebraic equations.
The algebraic equations are solved, then
the inverse Laplace tran

Power Series
Power Series Method
The power series method is the standard
basic method for solving linear differential
equations with variable coefficients.
Power Series
The power series (in powers of x x0) is
an infinite series of the form

Fourier Series
Periodic Functions
A function f(x) is said to be periodic if its
function values repeat at regular intervals
of the independent variable. The regular
interval between repetitions is the period
of the oscillations.
