Why won't you learn your trig stuff?

Yup pretty much, you can easily memorise these triangles now and the examiner should reward you some marks for computing them without a calculator (on a question that says without a calculator)

There is no requirement to "memorise" just to understand

it ain't relevant to the real world.

where am i gonna use it after the exam?

I made some notes when I learnt C3 last year that you can use. feel free to let friends use them if you need to, as long as you don't take credit for them yourself

link doesnt work it says loading and is frozen
Are you sure its all correct?

But thanks anyway!

that's weird I'll put it on my drop box and share the link, hang on

Tell me more about percentages so I can analyse. I would expect the same proportion if not more people to get A/A* in further maths as they're "geniuses". I don't know if you agree with the person I quoted, but he was suggesting that A-levels do not challange top level candiates, that's why I suggested STEP, you've only confirmed that STEP will be a challange. There are PLENTY of resources online, examsoultions, hegartymaths, intergralcalgirl and maths247 who has posted in this thread as well as various textbooks which students can use to try and learn the STEP content.

Also grade standardization is useless, after all, it suggests general studies is one of the hardest A levels.

Rough (not entirely sure) percentages for A/A*: 40% M, 65% FM, 90% AFM.

When I said "geniuses", I meant as in people neither of us have likely ever met (even on here), as I was using an extreme example.

Well, STEP is actually a strange one. It is not incomprehensibly difficult. It is an incredible achievement to be able to reach the point where you are comfortable with certain topics, but it is, by no means, rare for students to find questions in their favourite topic areas rather straightforward (though nerves can still mean it is easier said than done!)

Actually I will have to disagree with you there. The grades are intended to be standardised across difficulty rather than students performance (i.e. they do not always intend to meet 'quotas'). Low grades in General studies suggest that weaker candidates sit the exam whilst high grades in AFM (as above) suggest that stronger students sit the exam. Clearly AFM is much harder than general studies but it is still going to be roughly as hard to achieve the creation grades. That said, general studies is a bad example as it is regarded by unis to be the only exception to this rule.

?? Or mediafire?

drop box is easier for me cause its on my phone sorry for the wait xD if this doesn't work, I give up...

Young people have no difficulty memorizing hundreds of "pop" songs... so why can't they learn a dozen or so trig relationships ???

I'm not saying they should ensure equal proportions of people get A/A*'s in all A-level topics, I'm saying the students who sit further maths are A LOT brighter than the majority of students who sit maths and thus, a higher proportion of them are likely to get A/A*'s. If I'm honest, I don't really follow your argument so I might not reply to your next comment if I don't understand it.

Works
THanks!
I don't understand whats going on since im still doing functions atm

2 Simple triangles were taught to me by my teacher to have all the identities.

1) A 1 by 1 square cut diagonally down the middle giving a triangle with a right angle and 2 45 degree angles, 2 sides length 1 and a hypotenuses length root 2. This gives you sin, cos and tan 45 using SOHCAHTOA

2) An equilateral triangle with sides length 2 cut down the middle leaving a triangle with a right angle, a 30 degree angle and a 60 degree angle, 1 side length 1 1 side length root 3 and a hypotenuses length 2. This gives you sin, cos and tan 30 and 60 using SOHCAHTOA

I quickly and roughly (ie not to scale just so I could see them) sketched these triangles on every single question where I was required to use an identity for every A level Maths and Further Maths paper that I did.

You would rather they learn horse grooming, some ICT level 2 diploma or Media Studies etc. rather than an easier A level Maths?

I had huge battles with my teachers about this. Remembering trig exact values is utterly pointless. I timed it and it took me six seconds to calculate sin(30) with my scientific calculator. By memorizing it I save 5 seconds, so what? Besides there are equations in existence that enable you to work out some trig values without a calculator. A double reason for not memorizing them all.
