OCR MEI C4 [June 14th] Discussion

thanks anyway

Even if thats confusing... You can just find the magnitude of CD and AB and ratio it... They will accept which is rt5:rt20

Your welcome!
Good Luck

thanks, I tried the magnitudes and got root 5 and 2root5
so i think that's how they got their values

good luck to you aswell!

Not loOking forward to the comprehension paper :/

can someone please help me with this?

for part 7 iii june 11
it says CD = 1/2AB

but the ratio is CD:AB = 1:2

I thought it would be the other way around?

cramming in the form of learning some trig equations ?

Interesting.....

Seemed hard and easy at the same time

Most of section A was fine, except one question that I couldn't do.
Section B wasn't as great. I can't really remember the first question of section B. but the vectors one went pretty badly even though I can normally do vectors. I was running out of time towards the end and I could figure out how to do the last question.

Did anyone else get fractions for point B? I think I might have done that wrong. >_<

i got fraction for the last part of the last question when they ask u to find the intersection of BC with Oxz

i got a fraction for the last part of the vectors question. i think maybe 5/4 as lambda or something like that. i thought it was wrong
