  • This precalculus video tutorial explains how to determine the inverse of a 2x2 matrix. It provides a simple formula to determine the multiplicative inverse of a matrix. You can check to see if you have the right answer by multiplying the matrix and its inverse to see if you get the multiplicative identity matrix I2. This video contains plenty of examples and practice problems.

    If there is one thing I despise about math is the... lack of reason for each step.
    It's just, hey here's some 'matrices and inverse and yada yada'
    Yeah, just takes this and do that with it.
    Why? What's the goal?
    Well of course that'd involve knowing turbo calculus or something.
    What continuously trips me up is just the random addition of new variables that seem to come out of nowhere. I ask myself, why do we do that? And there's no answer that doesn't involve learning 3 new languages and entire new alphabet of symbols.
    Meaning it just boils down to 'just do this' which is fine until u just get blasted with new lexicon and terms ur unfamiliar with, which makes me want to define them but no there's no definition it's just- is? Like, what is even the goal?
    We're finding the inverse? Fine, that's at least a goal of some sort. Why are we skippitylackin the matricial bamferang now???
    Arrrgh, i frkn hate math.
