00:00:01.940 --> 00:00:03.589 A:middle L:90%
I was Just find the country cobian for the given
2
00:00:03.589 --> 00:00:06.469 A:middle L:90%
transformation X equals U plus view of square to wise
3
00:00:06.469 --> 00:00:09.439 A:middle L:90%
equal to u minus. Fear was heard to So
4
00:00:09.439 --> 00:00:14.460 A:middle L:90%
the Jacoby in is gonna be equal to Sorry.
5
00:00:14.599 --> 00:00:22.469 A:middle L:90%
Okay. Unequal to partial of ex respect to you
6
00:00:22.480 --> 00:00:28.230 A:middle L:90%
is one over the square to partial extractive e is
7
00:00:28.230 --> 00:00:30.339 A:middle L:90%
one over the square to two partial y. With
8
00:00:30.339 --> 00:00:34.210 A:middle L:90%
respect to you is one over squared to partial wise
9
00:00:34.210 --> 00:00:37.799 A:middle L:90%
work to be is negative one over the square to
10
00:00:39.659 --> 00:00:44.369 A:middle L:90%
That means that the determinant is going to be negative
11
00:00:44.380 --> 00:00:55.020 A:middle L:90%
1/2 minus a positive 1/2. And that is simply
12
00:00:55.020 --> 00:00:59.539 A:middle L:90%
going to be negative one and we are done.
