00:00:00-->00:00:03,123
Looks something like that. Yea I know
it is hard when you stand

2
00:00:03,200-->00:00:08
stand in front of it and no you are fine
just it hard when you

3
00:00:09-->00:00:14
standing in front of it and it is
to your back.

4
00:00:15-->00:00:17
This doesn’t have to be a great line.
Exactly you have kind of

5
00:00:18-->00:00:20
improvised your way through the

6
00:01:27-->00:01:30
Alright. That’s what I got. Ok.
So that’s fine that gives us

7
00:01:31-->00:01:36
something to talk about so that is perfect.
Alright so lets see

8
00:01:37-->00:01:40
in a couple of segments Casey has this
first portion of the graph

9
00:01:41-->00:01:47
um just that sum is increasing do
you guys agree? Yea.

10
00:01:48-->00:01:51,100
Ok he also has this point at about
.15 maybe zero he is on the x

11
00:01:51,200-->00:01:54
are you guys on the x axis right there?
Yea. Ok good so Casey

12
00:01:55-->00:02:00
why did you put the x axis right there?
Because both the graphs

13
00:02:01-->00:02:08
Ok because their sum, ok so he still
is showing an increase for at

14
00:02:09-->00:02:11
at least a while do you guys agree
with that? Yes. Ok

15
00:02:12-->00:02:20
Well let’s see and this is where
so Casey you are on the red line

16
00:02:21-->00:02:25
right here the Gilbert line. Yes.
Ok so you are on the curve of

17
00:02:26-->00:02:29
of this line what does that mean
for the other curve? It has to

18
00:02:30-->00:02:38
zero. Ok this I think this is where
the chandler function is zero

19
00:02:39-->00:02:45
and that is totally fine, this is what
I meant when I said one

20
00:02:46-->00:02:50
of these things where your shadow
covers the picture. You are on

21
00:02:51-->00:02:53
the red function if the other functions
value is zero so I think

22
00:02:54-->00:02:59
the value will be about there class
do you agree with cause

23
00:03:00-->00:03:02
actually here we said it was an increase
increase increase.

24
00:03:03-->00:03:08
What happens somewhere in here?
It has a decrease. Why will it

25
00:03:09-->00:03:12
start to decrease how about Gina?
Because both the graphs are

26
00:03:13-->00:03:21
decreasing. Both start to decrease
yes what about when this

27
00:03:22-->00:03:27
blue line starts to decrease.
It decreases faster and more than

28
00:03:28-->00:03:31
the red line. Ok that is also very
true so even though the red one

29
00:03:32-->00:03:36
one is still increasing is it perhaps
still increasing as quick as

30
00:03:37-->00:03:47
it was over here. Katie says no how come?
Because one is decreasing

31
00:03:48-->00:03:59
and then it will pull the other one
with it Ok good she said when

32
00:04:00-->00:04:02
Ok good um alright overall trend I
think we got up here lets just

33
00:04:03-->00:04:07
make sure lets see Casey has his sum
crossing through the x axis

34
00:04:08-->00:04:11
again but at this point they are no
both zero so what will it take

35
00:04:12-->00:04:19
someone other than Casey what will
it take to get this axis we were

36
00:04:20-->00:04:26
drawing how about Ryan. For the blue
one it is double negative.

37
00:04:27-->00:04:31
Well the blue one was double negative
over here and it wasn’t at the

38
00:04:32-->00:04:39
x axis. So for chandler to have a
negative change it doesn’t

39
00:04:40-->00:04:49
necessarily mean it will be on the
x axis. Say it louder I think you

40
00:04:50-->00:04:55
are fine. The line has to be like
this whole thing and so is the red

41
00:04:56-->00:05:02
line. It is like absolute value kind
of when the amount of the negative

42
00:05:03-->00:05:09
is the same as the positive. Because
if they are the same value one

43
00:05:10-->00:05:12
positive and one negative you will get
the same behavior and that looks

44
00:05:13-->00:05:16
the right spot too so that’s good.
