  • This is great thank you. Just found you so will be looking at all your videos. The more on Linear Algerba the better thank you again.

  • Exam is tomorrow so linear algebra videos will be good revision. What you want one on?

  • I would recomend using row reduction echelon form after finding the null space when solving for eigenvectors, makes life easier!

  • hey i understand how to diagonalise, but i dont understand how to make  Eigenvectors :(((

  • your content and stuff is really good - consider including proofs for stuff and your delivery won't be able to compete to other youtubers - they use tablets, screen recording, just a thought, good stuff though

  • lol 20% this was cool

  • oh you stuck in each eigen value in D that corresponded to the eigen vector column of C. in a diagonal way. but how do you know which eigen value to turn into an eigen vector first. ie it seems arbitrary that the 1 should in left column e.t.c. what if you turned the eigen value 1 into eigen vector second, then it would go in teh second column correct?

  • very useful. alot of this just isnt mentioned explicitly that you can use any value for a e.t.c in uni document. one question: how did you use the matrix C to find the values for D at the very end?

  • Thanks a lot!!! you really helped other soooooooooo much better than their so-called Prof

  • I'm amazed at how bad mathematicians are at being teachers!

    It's like anything else, there is a logical step by step process to solving this stuff. It's easy once you figure it out. But these guys never seem to be able to explain what they know in a simple step by step process. Their communication is HORRIBLE.

    I've learned nothing from this video! Just like many... many other math videos online.

    These guys are horrible teachers!!

  • aren't you meant to reduce it before you can multiply with x,y,z ?

  • the best explanation on this so far, ive watched many many videos though!!!
