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,
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
t
Lp means F ( s )=L[ f (
An example using Laplace to solve a differential equation:
x' x e
+ 2 = where
–t
u 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)
