MISTAKES:
Q23 should be False. For example v1 is the zero vector and v2, v3 are any two orthogonal non zero vectors.

Good luck studying for you Linear Algebra Final!

This is going to be insanely helpful! I will recommend my former students to watch this since I don't teach linear algebra myself and haven't done it for over a decade. I will also watch it to review it for myself. Thank you!

Omgggg, how did you do 109 linear algebra true false questions in less than 75 mins 😂😂😂 I did 111 in more than 4 hours 😂😂😂

This going to help students at UW-Madison because our mid-terms only consist of 10 T/F questions.

This is great! I’m sure that this will go viral, and I would love to see this for Calculus too! Keep up the great videos! :)

Nice video. I'd prefer if there was a slightly longer pause between asking the questions and showing the answer, even a second longer, so I have time to pause and consider it before you reveal the solution.

Q23 in my opinion should be False, for example v1 is the zero vector and v2, v3 are any two orthogonal non zero vectors.

Really appreciate all the hard work you're putting in!! Really helpful stuff!

Q62. The statement is true if A is in echelon form. It is not only true if A is in echelon form; consider A = [1, 0; 1, 1].

Thank you, we will have 20 true false and 20 mcq in this final exam 😁 happy new year

i have a question on #56, isn't the 2nd column in the example linearly dependent to the first column?

[CuteLittleHen]

Question three is confusing, because what if the field is not infinite, such as field Z7?

[eminbaybarstimurstudent]

I have a question on 82nd question, on 56:09, so what if our matrix is an orthogonal matrix, then A^T would be equal to A^-1, and the eigenvalues of A^-1 is 1/ λ. So wouldn't our eigenvalues change in this case ?

Could we get a calculus video that's just like this one please🙏🙏🙏🙏😭

[Aeldrion]

Q23 is wrong, right?
v1 could be 0, v2 wouldn't be a multiple of v1, you can take v3 linearly independent of v2, and {v1, v2, v3} wouldn't be linearly independent?

[balasavenedintulashabalbeoriwe]

Thank you professor. I have a wonder about the question 12. You say that this would be true if A had a pivot position in every column. Do you mean every column as well as row? Because for example A = [1, 0; 0, 1; 0, 0] has a pivot in every column but b = (0, 0, 1) (a vector in R^3) has no solution, yes? Or is the question saying, if there is a solution, it must be unique?

Very very very very very very very nicely 😀😀😀😀🥰

[yashmane]

Thank you so much! This is a very helpful resource

I think question 103 is wrong by definition, need c1, c2 to be non-zero

[jollux]

using this an hour before my final, legendary stuff here
