00:00This is question number 4, SSI's 2.3 and this is a big trade.
00:04You have 3-3 determinate and you have 3-3 equal to equal.
00:08D1 equal to D2 equal to D3.
00:11You can do this, D2 equal to D3 or D1 equal to D3.
00:14First, you have 1-1 and then you have 2-3 equal.
00:17If you have this and this equal to D3 equal to D3 equal to D3.
00:22I will take the second determinate and solve it.
00:28Now, I will take the first row and the second row.
00:32This is a big mistake.
00:34When you have the same row, you have to change the whole minus.
00:38Here, A, A, P and here, Y, P.
00:43Now, what is our problem?
00:47Who is trying to do this?
00:51I will take the first row and the third row and the third row.
01:17I will take the third row and the third row.
01:19Now, what will I do?
01:21Transpose.
01:24How will the third row be?
01:27Transpose means that it is complete.
01:33This row is row.
01:34This row is row.
01:35This row is row.
01:37This row is row.
01:38This row is row.
01:38This row is row.
01:39column
01:39will be
01:40ok

02:08Transports automatically
02:09Determinant 1
02:12So one thing is
02:13Determinant 1 and 2
02:16Now
02:17Determinant 3
02:20First row and second row
02:22Interchange
02:24Interchange
02:25This
02:27After
02:29R2 and R3
02:31Interchange
02:33First row
02:36First row and second row
02:38Interchange
02:39First row and third row
02:40Now this is D1
02:42D1, D2, D3
02:44This is the name
