You guys are just so thick

So showing that T^2 = I wouldn't get you the mark?
If you showed T^2 = I, then you have shown that T is self inverse

Yeah shall I whatsapp them to you
You have all the solutions? If so please send

Do you expect 75 to be full UMS? I think I lost a mark....T.T
Me too. I know I lost a mark because I misread that stupid geometrical transformation question and when I tried to prove they were perpendicular I didn't : OP and OR instead of OP and QR. Realised I had misread the question but then didn't again try to see if they were perpendicular. SOOOO GOODDDAAAMM annoying. I got the sf 2 part thou.

I have written down the model answers and gone through it with my teacher. if you want them sent let us know!!

Media (OCR) then FP2! They're keeping me under supervision until the afternoon.
I have to be escorted to lunch 😂😂

If T is self-inverse, T=T^-1, T*T = T*T^-1, T^2 = I.

i just calculated T^-1 and showed it = T, though if you calculated T^2 and showed it = I then you should get the marks (though you may have had to show why that implies T^-1=T)

Wait do people actually think this paper was hard?

I could see the 9b however everything else was standard. Maybe 8i (induction) however that wasn't that bad.

Anyways how did you guys prove that R is its own inverse?

I did Found that R^2 = I
R^{-1}R^2 = R^{-1} I
R = R^{-1}

I wonder if I will lose marks for this.

Also what was the geometry for the lines OP and (QR?). I think I said one was double the length of the other and they were in the same direction.
was for fp1 lol

Can you inbox them to me?

and how did you just change the middle part to a negative

I put brackets around the fractions and as the second part is positive the -1 outside the bracket means that it has to become negative

16. how many marks was 8(i) worth??
17. (Original post by dlc_01)
how many marks was 8(i) worth??
5 marks
18. For the geometrical relationship I put:
OP had been enlarged by a scale factor of 2 about O and then translated by the position vector of (4 -3).

Did the answer have to be it was "parallel"
19. (Original post by pv2)
the easiest paper by a long way
I hope you're joking, unless your trying to make me feel crap . Even if you didn't personally find that hard, there's no way that that was the easiest paper. The self inverse matrix and the geometrical relationship between the complex numbers on the argand diagram were unfamiliar questions, but still okay. But don't get me started on that series proof!

Also, being a slow worker, I found it impossible to finish the paper, unlike with the two I did last night which were fine to finish in under 90 mins. Hopefully someone out there gets me haha

Ok how dumb is this. The hall was literally EMPTY like there were only 3 people sitting the exam and the invigilators put us RIGHT NEXT TO THE CANTEEN. Out of allllllll the available space they sat us there.

**** I couldn't focus because the dinner ladies kept laughing and singing fmllllll
HAHAHHAHA I was sitting by the air vent and it was almost like a ****ing tannoy system cause kids were playing outside and LET ME TELL YOU I KNOW EXACTLY HOW MANY BARBIES JENNY HAS AND WHAT THEY WILL ALL BE WEARING TO THE TEA PARTY FFS 😂😂😂😂
