Problem 29 has a set of givens and gives us three statements and asks whether or not these statements are true or false.
00:07
The givens are, if you have a vector space v, which is non -zero and finite dimensional, and all of the vectors listed below belong to v.
00:15
Now let's look at a.
00:18
A gives us the vector space v1 to vp, tells us that this vector space spans v, then says then the dimension.
00:34
A v is less than or equal to p.
00:39
Now, in order to solve this, we're going to consider two types of spanning sets.
00:43
First, we're going to consider a linearly independent spanning set.
00:52
For a linearly independent spanning set, that means none of the vectors in this set can be written as a linear combination of any of the other vectors.
01:01
A linearly independent spanning set is also known as a basis.
01:05
And by definition, if we have a basis, the dimension.
01:09
Of v equals p.
01:11
Now the other type of set that we are going to consider is a linearly dependent spanning set.
01:22
If we have a linearly dependent spanning set, that would mean that some of the vectors in the set v1 to vp could be written as linear combinations of other vectors in the set.
01:32
Therefore, those vectors would not contribute to the dimension at all.
01:36
Therefore, the dimension of v is less than.
01:42
Understand p.
01:44
So a is true.
01:48
Now we're going to consider b once i erase all of this...
