or equivalently,
$id_S(x) = x .$

The area under your curve should just be:
N = numel(x);
dt = 1/fs;
df = fs/N;
y = fft(x)*dt;
area_y = sum(abs(y))*df; % which is also equal to: sum(abs(fft(x)))/N
energy_y = sum(abs(y).^2)*df;
If you really want "energy", then energy_y should be equal to energy_x:

Physics Forums - View Single Post - Acceleration as a function of displacement
actually as it turned out:

better put as
a(t) = 6 theta(t)
a(t) is just the second derative of theta(t), so
theta''(t) = 6 theta(t)
tossing away the 6 mentally for a second, what function equals its own second derative? e doe... | {"url":"http://www.physicsforums.com/showpost.php?p=1308630&postcount=3","timestamp":"2014-04-17T15:42:20Z","content_type":null,"content_length":"8255","record_id":"<urn:uuid:b845854e-a882-4ab4-b60e-7a1914a2c7a4>","cc-path":"CC-MAIN-2014-15/segments/1397609530136.5/warc/CC-MAIN-20140416005210-00174-ip-10-147-4-33.ec2.i... |

Why does the Kleene Hierarchy not collapse?

Consider some logical statement (I am talking about natural numbers all the way). P(x, y, z) is a computable statement:

I suppose this would have a Kleene level of 3.
