where are you posting them? thx
It wasn't too bad... I think some of the stuff were 4U material.
I never knew that in 3U you could be asked for induction other than Summation, Divisbility and Inequalities. I thought that the Miscellaneous Induction was explictly part of the Ext 2 course. Although I did manage to get it, although if I didn't do Ext 2, I don't know if I would've gotten it.
And that circle geom in Q7... wtf :S

The answer to circle geo in Q7 was very simple if you knew how to do it
Btw, I'm surprised that you didn't mark anything on your paper
Arggg... That's the thing with maths. You sometimes have to kick yourself to get an answer... What was it?
Also, I became sick in the MX2 exam, and have been sick since
I never mark anything on my question paper. It's just a habit I guess... I mean, it's not like they're going to read it or anything, so I tend to write all my 'thoughts' on the answer booklet itself, which possibly could mean a mark or so.

Here's my solution.Arggg... That's the thing with maths. You sometimes have to kick yourself to get an answer... What was it?

Consider triangle SPR
angle QSR=angle SPR+angle SRP (an exterior angle of a triangle is equal to sum of its opposite interior angles)
Hence, using given denotations,
phi=theta+angle SRP
Now for PT>0, (I.e. P is not the same as T)
angle SRP>0
This means theta<phi.
But when PT=0, i.e. P and T merge,
angle SRP disappears (S is the intersection of the circle by PQ.)
Hence phi=theta and theta is maximum.
Hmm, I always mark something on my paper, no matter what lol.. I found it easier to remember small things such as three decimal places that way. IO guess it's smarter to do it on the exam booklet so that the marker can give something for your thoughts, even if the actual working doesn't turn out to be completely correct.
Edit: I forgot to post the part (ii)
Let the base of the building be X.
TX^2=XR*XQ=h(a+h) [tangent squared=product of intercepts]
TX=sqrt(h(a+h))
which is the required distance.

I don't do Ext 2 maths, and I got the induction question. Dont know if its part of the syllabus, but I've definately been asked 'miscellaneous' induction questions before. It was the only part of question 7 answered...lol
Hey Tommykins... what happened to the fact that I was on your ignore list?
