Was it easy or was there a trick to it?Vanishing point anyone?
i had never seen or even heard of the 'vanishing points' for the cube, but i think i managed to just figure it out. if you measured one edge of the cube it was 3cm, then you could use that to form lines half way toward to vanishing points for the top edges, then for the bottom edges of the cube, i did a 3cm vertical line straight down form V1 and V2, then lined then with the vertices and drew another 3cm line.Vanishing point anyone?
haha yeah i dont even think i will get 1 mark fro my scribble, i think i found every possible angle and side EXCEPT the one we needed. Similar triangles would make sense because i was convinced that it wasn't possible with trig, but anyway.oh god the shadow question was confusing, did not know what to do there, I did similar triangles but I was just guessing, goodbye three marks
Was it not just the ratios of sides? Since they're similar triangle the flag height of 4 metres is to the man's height of 1.5m like the flag shadow of (I can't remember) is to the man's shadow. I got 1.115m (I think) and a friend also got that.haha yeah i dont even think i will get 1 mark fro my scribble, i think i found every possible angle and side EXCEPT the one we needed.

You had to work out how much he payed after all the monthly repayments, then subtract the original price of the item and the 10% deposit (I think this was the one with the 10% deposit) and then work out the remaining number as a % of the original price (-10%). If that makes sense...28 e) guys?
ive always had a bit of a problem with flat interest rate haha
(I'm looking at the question now) Oh, crap. I didn't divide by 3 for the annual rate. Dammit. The answer should have been 12%.wasnt it annual interest over initial amount x 100% so find the equivalent flat rate of interest?
I am quite confident I have never seen anything like that in my life. Is it in the syllabus?I only knew the vanishing point thing because of being an art student; You get taught about it when you're learning to draw buildings. It's the term they use to describe the way that all lines around you seem to head towards a single point, due to your perspective, if that makes sense.
Other than that, I didn't find it desperately hard and the bit of study I did really helped. I really enjoyed doing the estimate the seal population thing for some reason...
Trig will be my downfall; I didn't like the shadow thing.
Haha, I guess I was lucky. No, I don't remember being taught about it for math; perhaps it was something they assumed we'd know since it was basically asking 'draw this shape'. I still managed to screw it up, though, due to general lack of thought about what I was doing...I am quite confident I have never seen anything like that in my life. Is it in the syllabus?
