So advanced maths is definatly my hardest subject now!
Alot more work than higher!
Weve currently done the product rule and the quotient rule!
Anyone needing any help ill try and do my best smile.gif

We're going to be doing 2 outcomes at the same time, so it's quite confusing because it's like one day with one teacher, one with the other...ah well...i'm sure it'll all turn out fine in the end rolleyes.gif

and will, is that the product/quotient rule in matrices?

nope, differentiation.
And we're doing 3 differnt units with 3 different teachers!
Very confusing lol dry.gif

ah right...we've got 2 teachers.

at the moment, one's starting with outcome 1 and the other is starting with outcome 5....they're planning on meeting in the middle, and the first one to finish their 2 outcomes gets to do the 3rd...hardly much of a prize, is it? huh.gif

When we started advanced higher, 2 years ago now ( AHH ) we did binomial first which I found pretty easy.

I'm finding binomial stuff quite easy...the way the questions are confusing me more than anything else tongue.gif

Yeah, if you learn it instead of just copying it down, it helps more. smile.gif I'm doing maths at uni, and the first half of first year should be similar to AH, but slightly more in depth. I could put some in depth explanations up when I get the notes if anyone is interested...hell, if it gives me an excuse to fiddle with TeXaide again, I'm ectastic tongue.gif

what i found useful when i was sitting in the class was during study periods we all sat round the same table and worked through the work or whatever together as a team. Its not the same as copying btw its teamwork

If i am not here i am somewhere else

I preferred advanced higher to first year maths at uni, mainly 'cause uni is a mess tongue.gif In school, you get taught things properly. Even with tutorials it's only an hour a week, with probably more people than you've got in your AH class right now.

Even though I say that, I still prefer uni in general, lol.

Its interesting that advanced maths is about as far as i want to take my maths. When doing maths this year at university i really wasnt liking it at all. I cant put my finger on what it was but if i had done maths instead of comp sci i think i would be transfering to something else at the moment.

(its a bit of a ramble i know)

If i am not here i am somewhere else

Each to their own, I guess. I'm very interested in taking my mathematical knowledge way beyond the scope of AH level...

yeah i think it might have been just that. University or at least the one lecturer we had at the end was wanting to show us all these proofs of where all these equations and ideas came from. If you like maths then its interesting but i found all i wanted to do just pass the exam regradless of how much i actually understood.

whereas comp sci i want to know everything and understand everything in great detail. i think if anyone is unsure of where they want to go next they should use the test i jsut outlined there it works for me at least

If i am not here i am somewhere else

Maybe it's because I'm a physicist or it's just my way, but I found it really hard in AH Maths to remember some aspects of the course if I couldn't remember them. Like solving those 2nd Order differential equations (You'll get to those...they're fun wink.gif.

2nd order differnetial (non hemodunous) equations are well gd, all yi nd to do is remember the particular integral and then complementary function, stick them together and woosh you have 10 marks in the bag, adv maths is rly good fun, best course ever

I found first semester of Uni maths a complete bore, because it was an intro course which repeated a lot of higher and had a few bit of advanced highers thrown. But this semester I really found it quite interesting and some of the stuff was quite hard (like Cramers rule for solving systems of equations) and the 10 minutes we spent on Eulers rule, but the lecturers I had last semester were absolutely fantastic and really were passionate about the subject and made you interested. I think it depends on who you get teaching you the maths to be honest and what your tutor is like for tutorials. We get projects in maple as well which are related to the course, and are quite practical in nature so it makes the course content a lot more interesting. I changed my degree to include maths because of last semester (and the exam grade i got biggrin.gif).

2nd order differential equations are quite easy really, theres a lot to them but theres nothing outstandingly difficult about them. Its more fun when you get to partial differential equations.

Yeah they're easy to do (if you know what you're doing) but I never understood WHY you were doing what you were doing. You changed the left hand side to a form that was to work with and so because of that you had to alter the right hand side but why did you have to ADD this newly worked out side onto the left hand side. Whatever. It was just an example about how I personally had to see a proof to fully understand something

They give you these proofs in university if you continue with mathematics. The reason why they work is because of the property of linearity. The alternative name for this type of equation is 2nd order linear differential equation with constant coefficients. A differential equation is linear if it satisfies the following:

Suppose L(x)=f(x) is a representation of y(x), which is a differential equation, then it is linear if:

L(y1(x) + y2(x)) = (strictly equal to) L(y1(x)) + L(y2(x)).

A second order equation has the form a(x)y'' +b(x)y' +c(x)y=f(x).

The consequence of this is that if y1 and y2 are solutions of a linear differential equation then so is Ay1 +By2 where A and B are constants. We use this property to combine particular solutions into a general solution.

I wouldnt quite say anything you do in maths is fun, but it can be interesting at some points.
