2.5 Solve ODE by Laplace Transform
Example
solution
& + 2 x + 10 x = 0
&
x
x(0) = 0
&
x(0) = 1
Laplace:
&
L [& + 2 x + 10 x ] = L [0]
x
s 2 X s sx(0) x(0) + 2[sX s x(0)] + 10 X s = 0
1
s 2 + 2s + 10

2.4 Inverse Laplace Transform
Definition
f (t ) = L1 [F ( s )]
1
Where: L
is called the Inverse Laplace Transform Operator.
How to do it?
F(S) is simple
use table of Laplace pairs
F(s) is complicate
2.2 (b) Harmonic Motion
What is Harmonic Motion?
Consider a point Z, which moves along the circular orbit R with constant speed
Im (y)
z
R
t+
Re (x)
R radius of orbit or magnitude of Z (m or in.)
