Exemple de sortie écran :
The Laplace transform of F(t) is f(s)
/ oo
|
L{F(t)} = | exp(-s t) F(t) dt = f(s)
|
/ 0
A property of the Laplace transform is :
/t
| f(s)
L{| F(U) dU} = ----
| s
/0
Press return to continue.
Exemple de sortie écran :
If F(t) : t-> (1) then f(s) = (1/s)
Then :
/t
| 1
L{| F(U) dU} = --- f(s)= (1/s)*(1/s)
| s
/0
With s = (+2.000)
Then f(s)/s = (1/s)*(1/s) = (+0.250)
Press return to continue. .
