00:00:03.140 --> 00:00:05.540 A:middle L:90%
Here's the function U of T and we want to
2
00:00:05.540 --> 00:00:08.150 A:middle L:90%
think of the function as a composition f of G
3
00:00:09.039 --> 00:00:11.900 A:middle L:90%
and another way to write that would be with parentheses
4
00:00:12.160 --> 00:00:15.289 A:middle L:90%
, f of g of t. So, looking
5
00:00:15.289 --> 00:00:16.949 A:middle L:90%
at it that way we can tell that G would
6
00:00:16.949 --> 00:00:23.489 A:middle L:90%
be the inside function and f would be the outside
7
00:00:23.489 --> 00:00:28.160 A:middle L:90%
function. So when we look back at V A
8
00:00:28.160 --> 00:00:30.699 A:middle L:90%
. T what appears to be the inside function?
9
00:00:30.780 --> 00:00:32.829 A:middle L:90%
What we can see that tangent t is on the
10
00:00:32.829 --> 00:00:35.840 A:middle L:90%
inside of something else in two places. So we
11
00:00:35.840 --> 00:00:40.850 A:middle L:90%
could say that GFT is tangent e So what is
12
00:00:40.850 --> 00:00:47.579 A:middle L:90%
it inside of? So what is fft? Well
13
00:00:47.579 --> 00:00:49.649 A:middle L:90%
, we would have to have tea on the top
14
00:00:49.780 --> 00:00:51.869 A:middle L:90%
to place the g of t in there and we
15
00:00:51.869 --> 00:00:53.840 A:middle L:90%
would have to have one plus t on the bottom
16
00:00:54.009 --> 00:00:56.100 A:middle L:90%
to place a tangent of T in there, so
17
00:00:56.100 --> 00:00:58.770 A:middle L:90%
that would be our FFT. So f of G
18
00:00:58.770 --> 00:01:00.189 A:middle L:90%
would give us the original function
