Let us start with the solution.
00:01
So, let v1, v2, v3...vn be a set.
00:16
The spanning set g i .e.
00:26
V1, v2...vn is defined as the set of all the linear combination i .e.
00:48
Span of v1, v2...vn is equal to summation n i is equal to 1 to n alpha i vi modulus where alpha i are any scalar.
01:18
Now we have been given a1, a2, a3, a4.
01:22
We need to find the span of them.
01:25
So span of a1, a2, a3 and a4.
01:34
So this is equal to x1, a1, x2, a2 plus x3, a3 plus x4, a4 wherever x1, x2, x3, x4 are any scalar...
