ClassPad supports transform of the following functions.
sin(x), cos(x), sinh(x), cosh(x), xn, x, ex, heaviside(x), delta(x), delta(x, n)
ClassPad does not support transform of the following functions.
tan(x), sin– 1(x), cos– 1(x), tan– 1(x), tanh(x), sinh– 1(x), cosh– 1(x), tanh– 1(x), log(x), ln(x), 1/x, abs(x), gamma(x)
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
t
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:
x’ + 2x = e–t where x(0) = 3
ufourier, 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)
x
n
