00:00:00.940 --> 00:00:04.370 A:middle L:90%
So this problem similar to the previous problem, you
2
00:00:04.370 --> 00:00:07.049 A:middle L:90%
have to look at a textbook for the picture,
3
00:00:07.639 --> 00:00:14.289 A:middle L:90%
both for C one. Um, basically his ideas
4
00:00:14.300 --> 00:00:20.239 A:middle L:90%
you integrate. This is the cmas degree, which
5
00:00:20.239 --> 00:00:27.329 A:middle L:90%
is up upon lower buff who apparently her. And
6
00:00:27.329 --> 00:00:31.629 A:middle L:90%
this is your attention. Sorry, This is your
7
00:00:31.629 --> 00:00:36.020 A:middle L:90%
attention, pectoral kerf. And this is fact.
8
00:00:36.020 --> 00:00:38.270 A:middle L:90%
Or giving the vector field. So you're basically looking
9
00:00:38.270 --> 00:00:41.009 A:middle L:90%
at whether they're top product is a positive or negative
10
00:00:41.500 --> 00:00:43.759 A:middle L:90%
. That means if they're if they're about the same
11
00:00:43.759 --> 00:00:46.240 A:middle L:90%
direction, that is possible. If there about the
12
00:00:47.039 --> 00:00:51.320 A:middle L:90%
opposite direction there is active for C one, I'LL
13
00:00:51.320 --> 00:00:54.380 A:middle L:90%
say looking from the picture is it's not exactly the
14
00:00:54.380 --> 00:00:57.640 A:middle L:90%
same, but he's about the same direction. Um
15
00:00:57.859 --> 00:01:00.939 A:middle L:90%
, so the vector dot product should be positive.
16
00:01:04.040 --> 00:01:07.950 A:middle L:90%
And there for the second one, I'Ll say all
17
00:01:07.950 --> 00:01:11.980 A:middle L:90%
the doctor always not necessary. Exactly. The case
18
00:01:14.709 --> 00:01:15.629 A:middle L:90%
, I will say, is pretty close to the
19
00:01:15.640 --> 00:01:22.950 A:middle L:90%
case where, where this is always affect her is
20
00:01:23.109 --> 00:01:30.049 A:middle L:90%
sort off so perpendicular to his attention that throws across
21
00:01:30.890 --> 00:01:38.060 A:middle L:90%
and, uh, and probably us at the end
22
00:01:38.060 --> 00:01:41.900 A:middle L:90%
of curve There some negative parcel. I won't say
23
00:01:41.900 --> 00:01:46.250 A:middle L:90%
it's exactly zero papa for CTO. Oh, sorry
24
00:01:47.140 --> 00:01:51.450 A:middle L:90%
. For sea to it should be somehow small negative
25
00:01:51.450 --> 00:01:53.310 A:middle L:90%
number that is close to zero. And again,
26
00:01:53.310 --> 00:01:56.939 A:middle L:90%
this one usually should have the guy's picture, and
27
00:01:56.950 --> 00:01:57.450 A:middle L:90%
that should be clear.
