For this exercise, we have q.
00:05
A v .i is equivalent to e transpose sub i.
00:09
A.
00:09
E sub i is equal to 0 -0 -1 -0 -0 -0 -1 -0, which equals 0 -1 -1 -0, which equals 0 -1 -i and 0 -1 -1 -1 -1, which equals 0 -1 -1 -i and 0.
00:39
Then we have a sub 1, a sub 2, all the way to a sub n.
00:48
Then we have 0, 1, sub i, and 0.
01:05
And this is equal to a sub i1 times 0 plus a sub i2 times 0 plus a sub i, i times 0, plus a sub i, and this equals a sub i...
