00:00:00.960 --> 00:00:04.599 A:middle L:90%
this problem asks us to use our calculator to evaluate
2
00:00:04.599 --> 00:00:07.190 A:middle L:90%
both of the following triggered a metric functions. And
3
00:00:07.190 --> 00:00:09.589 A:middle L:90%
then after we've evaluated them, we're supposed to round
4
00:00:09.589 --> 00:00:12.810 A:middle L:90%
our answer to four decimal places. Now, when
5
00:00:12.810 --> 00:00:14.849 A:middle L:90%
we first look at these two problems, the first
6
00:00:14.849 --> 00:00:19.089 A:middle L:90%
thing we need to notice is that our angle measures
7
00:00:19.100 --> 00:00:21.510 A:middle L:90%
are not in degrees, but they're in radiance.
8
00:00:21.859 --> 00:00:25.530 A:middle L:90%
So for the 1st 1 we have to calculate co
9
00:00:25.530 --> 00:00:31.359 A:middle L:90%
tangent and co tangent is simply the reciprocal of tangent
10
00:00:33.740 --> 00:00:43.250 A:middle L:90%
. So Cho tangent of 1.35 Sampley equals one over
11
00:00:43.609 --> 00:00:48.549 A:middle L:90%
tangent of 1.35 radiance. And when you plug that
12
00:00:48.549 --> 00:00:50.789 A:middle L:90%
into your calculator, you're going to find that that
13
00:00:50.799 --> 00:00:58.950 A:middle L:90%
answer round into four decimal places. Zero 0.22 for
14
00:01:00.240 --> 00:01:03.969 A:middle L:90%
fine. Now, to do part B, all
15
00:01:03.969 --> 00:01:07.670 A:middle L:90%
you have to do is plug tangent of 1.35 into
16
00:01:07.670 --> 00:01:12.250 A:middle L:90%
your calculator and you'll find that that answer right there
17
00:01:12.890 --> 00:01:22.150 A:middle L:90%
is equal to 4.4 552 and there you have it
18
00:01:23.140 --> 00:01:26.430 A:middle L:90%
. Those are both those angles evaluated to four decimal
19
00:01:26.430 --> A:middle L:90%
places
