Linear Algebra Basis & Dimension
Lecture Description
When you’re given a square in an algebra class problem, one of the question you might be asked is to find the area and perimeter. In linear algebra, you would be give a vector space and asked to find the basis and the dimension. These are two properties of vector spaces that will come in handy later on in the course, but are very important to understand now. After these vector space properties we’ll discuss a unique type of linear system that we mentioned earlier.

Are orthogonal vectors always linearly independent, and are linearly independent vectors always orthogonal?

Maybe wrong place again, but could you explain the Hector triple production? I know hos to calcu?ate it, but I havet no idea och what I'm calculating?
Thanks again for your great Messina!

Raffi.
For the first, I totally love your videos. You are a really really great teacher, so keep it up! :)
For the second, are you going through how to use the determinant to calculate the area or the volume of a Geometric shape? I can't seem to find it anywhere :( Maybe a little bit off topic but i hope you will answer my question relative soon. Thank you very much for all of your hard work, I don't think you know how much it helps me.
Joel

Hi Raffi: Just a question for Theorem 2: is the following true
a) S is a subset of V (not a subspace)
b) w=SpanS is a few of the vectors in S (so a subset of S if not all the vectors in S are required to span S)
Have a great day!!

Thanks for the quick explanations in the beginning with unit vectors i, j, and k; it definitely helped me get a better understanding for the basis of a vector space.

if you solved the system and you are left with the trivial solution, is that enough to show that all the vectors in the set are basis? as i've seen a few examples which show the solution involving the inverse of the matrix, im not entirely sure why the inverse relates to the unique solution, would you be able to explain please, thanks
