(33) Jump to unreadPost a commentDo I get a free Maths GCSE? (or O-level as they used to be in my day)...

Will pay an extra £1 + p&p.

Good find though

According to the equation as originally specified, b = y - mx.

You must be thinking of an entirely different equation where b = c.

Line gradient m , the intercept on y -axis is c

I think its just a case of where in modern maths GCSE they have changed the letter used from C to B like they did when i did my degree and they changed i to j.

still good price for the deal though

This would undoubtedly tie in to the "old" specification.

It's a good deal but you can usually get them from schools, websites tend to be better at this as long as you know what to search for i.e. what you want to learn and the questions evolve every year especially now to include more functional skills/maths.

No need - plenty of up to date on-line resources. Try 'MyMaths' - my daughter uses this and sometimes Bitesize.

The answer is %&*@"!^$%()&*(%^*$&£$%^"%"$%$%&%!!!! LOL!

LOL seriously?? m and c are just constants...they could be represented by any symbol. The equation could be y=ix+k...it's only cause the english syllabus specifies it as y=mx+c as it's easier to remember that c=constant

y = mx + c(as I was taught it) is to make it clear thatm = a multiplierandc = a constant. I'm scarcely surprised that the Yanks don't conform; they don't speak English (and they call it 'math' rather than 'maths' too). :?q=de + o

is a linear equation !!!

Good find though

b is the new c. :)

Don't you do change in y values over change in x values for the gradient? :thinking:

Did you do an engineering degree? They often use j for sqrt(-1) instead of the i that mathematicians use.

I hope not, I live on the coast.

Yes, dy/dx :)

This would undoubtedly tie in to the "old" specification.

not sure at the gcse level but isn't there some variation on the exam content and syllabus dependent on the exam board you school uses. If they are changing the syllabus they will probably be taking things out.

They do in Physics as well so as not to confuse with i = current.

which for mx + c is equal to m. I suspect not many GSCEs contain basic calculus though :)

_______________________________________________________________________

One equation relates to a straight line graph while the other concerns the slope (rate of change) of that straight line?

:?

Also, integrating the gradient (m) will give you mx + C so it makes sense that way when you continue Mathematics into A-Level.

It's just conventional. Like English. You can always use different letters and words but then you'd have to go through the hassle of explaining everything again.

Indeed so - so if it ain't broke, why fix it? And why, oh why, do so many people (including 'respected' financial institutions) nowadays tell us that an amount will be 'debited

from' an account. :shock: A monetary amount is debited (or credited)toan account, as every book-keeper, accountant or bank employee knows only too well. 'Debited' means 'charged', not 'taken'.Thats all we've had to learn at A-Level :? :w00t:

Know that and you got 4% of the paper in the bag :lol:

That's almost enough for a pass these days, isn't it?

Best advice I had from 'sir' when sitting my Applied Mechanics A-Level yonks ago was to choose the scale of my graph carefully - as otherwise the point of intersection might lie on the next-candidate-but-one's paper! Yes, it could happen. :oops:
