    As a foreigner I would like ti praise your serious, decent, clear and well standardized pronunciation of English. Something of one accord with the brightness of your effective didactics. Greetings!

    Here's a question: what is your interpretation of the meaning of a determinant?
    Complicating matters is, I've heard the term used in a couple different contexts. one of them is, in the quadratic formula, the part under the square root is sometimes called the "determinant", and I'm not sure why. I don't get the common concept behind it all.
    I have a fondness for determinants though. You can use them to solve systems of linear equations (Cramer's Rule). You can use them to determine if systems of equations are linearly independent.

      Discriminant under the square root. I used to mix them up, too 😀. I think determinant arises from a system of equations. I'll do more research.

      @@PrimeNewtons Thanks! I mean, only if you're curious about it. I don't want to make you do extra work.

      Determinant 3x3 is the volume of parallelopiped
      Determinant 2x2 is the area of parallelogram

    Chosen column can be expressed as linear combination of vectors then determinant will be sum of determinants
    and in each determinant in that sum chosen column is replaced with that vectors
    Here is example
    det([[a_{11},bv_{1}+cw_{1},a_{13}],[a_{21},bv_{2}+cw_{2},a_{23}],[a_{31},bv_{3}+cw_{3},a_{33}]]) = b*det([[a_{11},v_{1},a_{13}],[a_{21},v_{2},a_{23}],[a_{31},v_{3},a_{33}]])+c*det([[a_{11},w_{1},a_{13}],[a_{21},w_{2},a_{23}],[a_{31},w_{3},a_{33}]])
    This with cofactor expansion can be helpful if we want to expand characteristic polynomial written in the form det(A-λI)

    Here's another video I need to watch again. Sure seems like a lot of opportunities to make silly computational errors!!

    hey, thanks for the video, sir. I can understand the calculating process, however, I would like to know why do we do it like this? Any geometric interpretation please?
