Would my understanding for this question be correct?



Also what is the other method of doing this question? How would we change the base?

why confuse yourself when you have an easy simple method. it is just a waste of time

Because confusion is the most intuitive route to understanding. Only if you have once been confused about something can you be sure that, if you ever become confused about it again, it is possible to un-confuse *yourself* without asking someone else.

not confusion. it's understands and asking why to your doubts. confusion makes head ache! and maths is something to write and re-write several times to get the answer.

Maths is something to jump in and get your feet wet

Having alternative approaches to hand is essential for when you accidentally jump in the deep end

True.

Though this alternate approach seems a bit pointless. But kudos to the OP for asking.

I think you're wrong on every count, actually. Understanding is, of course, right; asking why is always right; but I don't think either is enough to lead to remembering. (It used to be, for me, but I've aged and got stupid.) It's all very well to understand something, but if you can't discover it for yourself, then if you ever forget it, it's much harder to re-discover it. Confusion is part of the process of discovery - if I experience confusion over it, and I find a way to beat the confusion, the process stays with me much more than the actual result does. (Obligatory relevant plug: http://www.patrickstevens.co.uk/wordpress/archives/584 )

Maths isn't something to write and re-write. It's something to understand, and understanding comes through discovery. Understanding doesn't come from writing and re-writing - it comes from actually grappling with a problem (possibly making your head ache along the way).

maths is more of practise. to understand the questions and try different numerous questions. practise maketh a man perfect.

Correct. I looked at it, said 'yes, I get it, C2's cool' to myself, then looked at somebody's post on a C4 "Parametric equation", and I was like... WTF... Will this A2 stuff genuinely click in my head next year (currently Year 12)...?

Well, that's re-assuring, if a bit unbelievable at this stage Cos that's the same story then, with this year's Maths. Indeed, "everything's really hard", till eventually it did all just click later on (this year).

Still, I hope C3 and C4 just won't be as daunting as it's made to seem.

No

Understand first

Everything's really hard until you understand it. Then it becomes obvious.

this is why you cannot solve any problems and you keep posting doubts on TSR!
Anyway stop quoting me again. Enough!!! No arguements

For me, at least, it all just slotted neatly into place alongside all the rest of my knowledge. It was FP1 and 3 where things were sometimes so completely new that I had no intuition about them at all.
