Title: need help methods
Post by: xSkittles on May 18, 2010, 12:01:14 pm
Guys, i am aiming for a 30 in methods but i studied so hard however i keep getting e's for my sac.. can i still get a 30?
i got E for 1st sac and E for snd sac?

Keep working hard, study well.
What you put in is what you get!

Also, if you are finding that you don't even understand what your teacher or textbook is trying to say, it might be best to get a tutor who can provide you with valuable 1-on-1 teaching.

if you think your working really hard, and still not getting results, concider changing how you are learning, because methods is just all about hard work. Make sure you are understanding the fundementals behind the concepts as this is the key to doing well. memorising formula after formula will not help you much at all. Learning how you get these formulas will allow you to see the limit of each formulas applications and means you don't ahve to remeber as muhc formulars, you just remeber HOW to ge thte formula with the knowlege you already have.

And you having two e's is not detrimentally bad, as long as you do well for the rest of the year. gl:)

and yea, a tutor might help if you are still really struggling

Yeah, deriving theorems is great practice :) Especially for geometry, which doesn't exist in the methods syllabus. What do you do in methods 3/4? Polynomial graphs, functions and relations, prob, trig (are there those identities yet? or just graphs), and calculus?

3/4 is basically functions (inc. polynomials etc.), trig (just two identities: tan=sin/cos & sin^2 + cos^2 = 1), explog, calculus (lots :)) and probability

But yeah, deriving formulas are great practice! And also make sure you understand and can solve all of the typical types of problems that you are likely to get (textbook exercises are handy)

Wait, so no double angle formulas, half angle formulas, addition/subtraction, cosine and sine rule etc... so how do you derive theorems if none exist in the methods syllabus? LOL

Lol, none of them I think (well addition and subtraction is disputed at the moment, our teacher (an examiner) says it's in)
But deriving log laws from the index laws is useful

yep, plenty of log laws to derive, they can be fun

you can derive the quadratic formula (LOL)

Havign a really good grasp of limits can be pretty good with heping your understanding of graphs in general and caculus

LOL yeah I derived that years ago :D

Lol, didn't we all...
Also, I would suggest using algebra to find derivatives using first principles, it is good practice with limit manipulation :)

Yeah i remember this, although proving that the first derivative of the quadratic is equal to its discriminant is far more adventurous and cool. That was fun.  ::)

omg, just got back from uni maths lecture AND WE JUST DID LIMITS. Thouhg it was pretty conincedental.....omg multivarible caculus.....insane stuff......

what? the discriminant isn't even a function of x...?
