Posted February 19, 2007 Good lord, how did i get a B for Maths?! Glad i dont have to do it anymore, though it was a good 5 years ago now i guess. Still, thought i'd remember still :S Share this post Link to post Share on other sites
Posted February 19, 2007 You should always rearrange quadratics so that they are equal to 0, then try and factorise. If you can't factorise them, use the formula (or complete the square, which is effectively the same thing). This time last year I could do all of those things, but I can't actually even remember how to start doing it anymore.. I'm so glad I don't do maths anymore.

I'm not going to take it for A-level, i don't like maths and the teacher is scary. Share this post Link to post Share on other sites
Posted February 19, 2007 'tis a pity for all of you... maths actually becomes an interesting subject at A-level. I found all this rubbish boring as well. In my opinion, they should get rid of ladders leaning against walls and put calculus on the GCSE syllabus. Anyway, although I'm doing double maths A-level, I'm not actually doing maths at uni, so I don't swear my undying allegiance to it... though it does run the universe.

If you can't factorise them, use the formula (or complete the square, which is effectively the same thing). yeah I realised that after I had posted. I couldn't be bothered to try and factorise so i just used the quadratic equation. I got the question right but then I had to go so I didn't get enough marks. Will have to have another go at it.

Posted February 21, 2007 I don't do homework anymore. All I get is exercise questions, when I clearly know how to do those questions and don't need the practice. It just seems like needless chores that are only there for the sake of extra work. Share this post Link to post Share on other sites

Posted February 22, 2007 A-level maths is booooooooooooring, im onto trigonometry at the moment and all we are doing is simply what we did at GCSE! WHY also i found logarithms (sorry forgotten how to spell today) a little difficult. For those who are taking A-level, have you taken your C1 right? how'd it go?

Here it is How retarded do those kids look? What is it is that the teacher is lazy and can't be arsed to mark "real work" but she's quick enough to have a moan when we dont do this. And its flash based so when you refresh you get a whole new set of questions and you cant go back and check them/ or change your answer. Share this post Link to post Share on other sites

WHY also i found logarithms (sorry forgotten how to spell today) a little difficult. For those who are taking A-level, have you taken your C1 right? how'd it go? Yeah, I've taken C1... I got 92. When I said A-level maths was interesting, I didn't mean C1... it starts to get interesting in C3 and 4... unfortunately, you have to do double maths if you want the really interesting stuff, which most people refuse to do outright.

Posted February 23, 2007 A level maths is shite because it just tells you exactly what to do when. So prescriptive. I'm really struggling with the maths part of my course atm because A level really doesn't set you up that well... Share this post Link to post Share on other sites
Posted February 24, 2007 I’m doing it on osmosis in potatoes. I’m using distilled water, 0.5m and 1.0m (this is just the pilot). Anyway, the potato piece in the distilled water has an increase in mass (10.5 to 10.8) and the others have a decrease in mass. I need to work out the percentage change. I get a decrease % for 0.5m and 1.0m, so I get a minus on my calculator. Here’s where I’m confused, I need to do a graph. So, do I put a minus y axis? Any help would be great. I’m terrible at maths.

Posted February 24, 2007 I did the exact same experiment, What We did was we calcuated the average increase of size of the potatoes and put it in the graphs.... But I got a C at it.... Share this post Link to post Share on other sites

Yes, you do want a y axis that covers positive and negative, as if something gets lighter, its percentage increase is negative. Incidentally, when you say "0.5M", do you mean of salt solution?

I've done that experiment about 4 times. its stupid that i could write out a full practical report now without even looking at anything and just faking some results.
