Laplace Transform of a Differential Equation

The laplace command can be used to solve ordinary differential equations. ClassPad does
not support System of Differential Equations for laplace.

Syntax: laplace(diff eq,

x

,

y

,

t

)

diff eq -- differential equation to solve

x

-- independent variable in the diff eq

y

-- dependent variable in the diff eq

t

-- parameter of the transform

Lp means F(s)=L[f(

t

)] in the result of transform for a differential equation.

An example using Laplace to solve a differential equation:

S fourier, invFourier

Function: “fourier” is the command for the Fourier Transform, and “invFourier” is the
command for the inverse Fourier Transform.

Syntax: fourier(f(x),x,w,n)

invFourier(f(w),w,x,n)

f(x) -- expression

x -- variable with respect to which the expression is transformed with

w -- parameter of the transform

n -- 0 to 4, indicating Fourier parameter to use (optional)
