ants Claressa when you raid here. So we're gonna
2
00:00:03.029 --> 00:00:06.089 A:middle L:90%
find the curve length of the curve. So we
3
00:00:06.089 --> 00:00:16.260 A:middle L:90%
get the Y over DX to be signed two x
4
00:00:19.739 --> 00:00:27.600 A:middle L:90%
, and we're going to square both sides and add
5
00:00:27.600 --> 00:00:31.179 A:middle L:90%
one to the expression. So when we do that
6
00:00:31.179 --> 00:00:33.450 A:middle L:90%
, we get one plus d y over tea cups
7
00:00:37.439 --> 00:00:46.929 A:middle L:90%
square, it goes one plus square two x is
8
00:00:46.929 --> 00:00:54.590 A:middle L:90%
equal to And when we recall the identity the hyperbolic
9
00:00:54.590 --> 00:01:00.000 A:middle L:90%
sign and coast on eternity we get gosh square of
10
00:01:00.009 --> 00:01:06.450 A:middle L:90%
two months. Don't we square? Root the expression
11
00:01:26.439 --> 00:01:30.359 A:middle L:90%
? No. We're gonna integrate from 0 to 1
12
00:01:56.799 --> 00:02:05.329 A:middle L:90%
. Caution two X t x. This becomes equal
13
00:02:05.340 --> 00:02:12.229 A:middle L:90%
to one. Have a sign. I probably like
14
00:02:12.229 --> 00:02:20.669 A:middle L:90%
function of two x from 0 to 1. This
15
00:02:20.669 --> 00:02:28.750 A:middle L:90%
is equal to e square minus eat the negative two
