00:00:00.240 --> 00:00:06.250 A:middle L:90%
operation of cosign in order to find what the degree
2
00:00:06.250 --> 00:00:09.849 A:middle L:90%
measure would be if the co sin of X equals
3
00:00:09.849 --> 00:00:13.000 A:middle L:90%
one half. So if you're using a T 84
4
00:00:13.000 --> 00:00:15.750 A:middle L:90%
or in 83 in order to punch this season,
5
00:00:16.539 --> 00:00:19.989 A:middle L:90%
you would punch in your second and then you would
6
00:00:19.989 --> 00:00:23.789 A:middle L:90%
punch in your coast on button and above the cosign
7
00:00:23.789 --> 00:00:25.690 A:middle L:90%
button is where you're going to see that co sign
8
00:00:25.690 --> 00:00:27.269 A:middle L:90%
. And it's not that negative one that just let
9
00:00:27.269 --> 00:00:30.000 A:middle L:90%
me know we're doing the inverse because we have our
10
00:00:30.000 --> 00:00:32.850 A:middle L:90%
cosign we just need to find with that degree is
11
00:00:33.340 --> 00:00:37.060 A:middle L:90%
and then you're gonna type in one divided by two
12
00:00:37.939 --> 00:00:41.969 A:middle L:90%
. So we're gonna pull up a similar one.
13
00:00:44.439 --> 00:00:46.090 A:middle L:90%
So let's pull in. And now this one,
14
00:00:46.090 --> 00:00:47.899 A:middle L:90%
we're not gonna press second, but we are going
15
00:00:47.899 --> 00:00:51.509 A:middle L:90%
to do the inverse of cosign, and I have
16
00:00:51.509 --> 00:00:55.079 A:middle L:90%
a parentheses that's already popping up. Since I don't
17
00:00:55.079 --> 00:00:56.689 A:middle L:90%
have a square root or anything, I could just
18
00:00:56.689 --> 00:01:00.490 A:middle L:90%
put one divided by two. And that tells me
19
00:01:00.490 --> 00:01:03.140 A:middle L:90%
that my my ex, if co sin of X
20
00:01:03.140 --> 00:01:07.920 A:middle L:90%
is one half, that means my ex is going
21
00:01:07.920 --> 00:01:11.670 A:middle L:90%
to be 60 degrees
