I came across 2 very unusual (and possibly hard AS questions) from a C2 paper.

Attachment not found



The version you see here is my modified version which I just added to my resources.

I will put solutions up soon.


Interesting questions! The second one looks like a lot of sin/cosine rule at first glance.

clearly it is but how?

Is this OCR?

Q2 was straightforward, Q1 looks more difficult. Can't believe I have nothing better to do at midnight on a Saturday than fun C2 maths :wink:

No it is not straightforward ... I messed it up
I missed a part
( ... the wine)

Which exam board is this from? Don't even know where to start with either of them:confused::confused:

Blame the wine :wink: did Q1 too now (well I think I have, seeing as it isn't a show that)

Both of them really!
Q1 I've never seen anything with letters and tan or whatever it's getting at haha
Q2 I don't understand where you'd start cause with sine and cosine rules you need angles and you haven't got any

Probably because it's late at night but still it's going to really bug me haha, hopefully this isn't from OCR MEI? Otherwise I'm screwed:s-smilie:

Q1: You can find alpha directly as it is given to you. Use this to form an equation in beta and gamma (angles in a triangle add up to...)

Q2: The only way you can find the area of ABD is using the area sine rule, so you need to find the angle at B.

That's great thanks got Q2 now but Q1 is a mystery haha! If this came up in a C2 exam I may cry!:colondollar:

Worked out alpha but for beta and gamma I just don't understand how you get them? I'm not your A* maths candidate so it's probably out of my reach:redface:

these are from an actual UK 2014 exam!!!

the second question I have made harder by removing one structured part.

Are they?! They look like questions you might get on an AEA paper. What is the difference in Q2? My laptop has died can't see the original pdf.

Q2 is very very hard.

It is asking in part (a) to find AD
then the area of ADB.


look at it tomorrow sometime and you are fresher.
