If you went to the CompSci admissions talk, did you think that the sample interview question they gave was really easy? I wonder if the actual interviews are like that.


I think it impressed the parents, but yeah that was literally C1 territory. I expect in the interviews they do literally push you to where you can't answer it off the bat :smile:

After open day I'd probably go for Christ's or St John's. Although I could change my mind.

Trinitys **** mate...you could never convince me to apply there, not even if u offered me all their wealth

Yeah, but with trinity, just a look at the college is enough.
How would you solve sinx+2cosx=1 \sin{x}+2 \cos{x}=-1 ?

Harmonic form is the way to go.

Write the LHS as Rsin(x+a) then expand and match coefficients.
Has anyone seen Clare?

Here you go maths people. Nice neat problem. ImageUploadedByStudent Room1435963609.300752.jpg

Still can't get it to work with the answer in the book lolz

TBH John's is a great college - but is often the subject of a bit of banter from everyone else.

Yeah I've noticed. Several Oxford related jokes.

You might be doing something wrong.
Rsin(x+a)=-1
sin(x+a)=-1/R
So two possibilities
x+a=arcsin(-1/R)+2npi
x+a=pi-arcsin(-1/R)+2npi
pick values of n to keep within range (if given).

Got it, just got R and a mixed up with putting it back into the equation to find x so I wasn't getting the right answer
:goodnight: Thanks for the explanations though I've never seen it in a generalised form before, that could come in really handy! I usually just use a CAST diagram but it can become awkward if the range is <4pi
