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'
3. 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.
4. Thanks!
5. 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.
6. Well that went very well
7. That was so chill. Might as well have been C1 haha
8. Hii
What did you guys do for 5)ii) the one with r and k etc etc

And what did people get for the area in the last question
I have to get something crazily high after failing m2 yesterday :'(
9. Could someone make an unofficial markscheme please? I didnt get a few questions and am puzzled...oh and a copy of the paper would be good!

k=1/3

area =4*6*8 = 192
11. Well that was hard
What do you think is the mark for getting an A. For me I think it's in the 50s

Yep, and for the z^4 equation i got that all the roots stayed the same with an extra solution, by inspection z=1 also
13. That was so hard; it was the hardest paper I've done so far.
