I crammed for uni maths exam last week. And I did hell good in it...usually Ive done the week a few before so by the time the test comes around Ive forgotten it.Originally posted by :: ryan.cck ::
soo tru maths is like one of the only subjects u CAN NOT cram
u need fukloads of practice to be gud =D
Actually, in a direct question like "Integrate cosecx" is where you will have to derive it, and not just write the answer. The reason i memorize them is so in a q7/q8 question, i don't have to waste valuable time deriving it when there is another hundred things to do in that question.Originally posted by Constip8edSkunk
well how many question in the exam is gonna ask you straight how to integrate cosec x, besides those few 1 mark questions...
I really dislike memorizing textbook methods. I find it's quickest (and more fun) to look for the shorter solution (particularly in the later questions).its those harder questions that you cant cram for, where you actually have to practice to memorise the procedure in approaching that certain type of questions
Yep i understand, but as i said above, it's always good to know when it's in part of a solution where the question doesn't directly ask for it (but requires it for the final solution). If that made any sense?Originally posted by flyin'
IMO, ND, alot of the time, especially in Extension 2 Mathematics, they require you to derive certain formulae (as early parts of the question). Few people walk into an exam knowing the integral of cosec, or the normal of a hyperbola!
Yes, it does! Especially, if you accidently derive the wrong formula!Originally posted by ND

you should know how to dervie stuff... and that comes thru doing your maths homeworkOriginally posted by ND

edit: I get what yoru saying now.Originally posted by ND
I disagree about not being able to cram for maths. How many people know the integral of cosecx, or the equation for the normal of a rectangular hyperbola at P(ct, c/t)? There's not enough time to derive these sorts of things during the exam (unless specifically asked for it). And of course there is the induction concluding statement.
