    Hi! just doing some revision for the exam tomorrow, sorry if this is a stupid question but if you times a matrix by its inverse you get the identity matrix right? but this can't work the other way can it? i.e. if you times a matrix by the identity matrix you don't get the inverse? So nervous!
    No, if you multiply a matrix by the identity you get the original matrix back again - that's the definition of 'identity'

    :facepalm: why don't people look to see if threads have already been made before making new ones?

    anyway expecting inverse of a 3 by 3 to come up.

    I'm retaking it as I got 67UMS last year, hoping to bump it to an A now though.

    EDIT: Oh, this is MEI, never mind lol. I should really learn to read.
