Thanks! Not sure why everyone was shitting bricks over Q16 but

The syllabus only places restriction |r| < 1 for limiting sum
I doubt it, ask InteGrand or CarrotsticksTrue. I hope they don’t take marks off for that
Easier than what I expected.How did you find it?
I did the exact same, I spent a bit of time proving similar triangles and what not but didn't get anywhere, by the looks of what everyone else is saying I doubt I will get marks for that but I hope they are generous to give me at least one mark.Easier than what I expected.
How did people do the proof question at the end of 16? It was probably obvious but I ended up skipping the 3 mark cuz I couldn't wrap my head around it at the time (Part i. Prove that triangle ACE is isosceles) and doing the 2 mark (part ii).

Looking at the solutions I think I should have revised proofs to do with parallel lines. Ratio of intercepts of parallel lines just didn't occur to me. And it's funny cuz during the exam I thought BD=DE but just didn't know how to prove it. But yea, hopefully you can score a mark for writing something down for proving similar triangles.I did the exact same, I spent a bit of time proving similar triangles and what not but didn't get anywhere, by the looks of what everyone else is saying I doubt I will get marks for that but I hope they are generous to give me at least one mark.
got out of the exam room and thought 'i wonder if they told us BM=MC for a reason?' turns out they did and I just didn't do anything with itLooking at the solutions I think I should have revised proofs to do with parallel lines.
