Maths C1 - 13th Jan 2012

Hey,

I was just wondering if someone could tell me all/most of the formulas that I'll need for the C1 Exam on the 13th Jan.
I havent started revising yet :frown: and i dont really get most of the stuff thats in the exam, does anyone have any tips etc.

Thankss.

You haven't revised?

Good Luck...

Sn=12n[2a+(n1)d]Sn = \dfrac{1}{2}n[2a+(n-1)d]

Sn=12n(a+l) Sn = \dfrac{1}{2}n(a+l)

These formulas are used to find the sum of a sequence, with a being the first term, d being the common difference and l being the last term.

Oh, and this is required to find a specific number of a sequence:

Un=a+(n1)dUn = a+(n-1)d

Thanks for that, hopefully it will help :biggrin:

Which examiner? it makes a difference as C1 & C2 content is split up differently by different examiners.

For Edexcel:

Also for Edexcel, worked solutions to past paper questions here:

Then maybe it's time to stop making excuses for yourself, open a C1 book and learn the content.

to find sum of series:
a-1st number, n-term number, d-difference
Sn=12n[2a+(n1)d]Sn = \dfrac{1}{2}n[2a+(n-1)d]

a-1st number, l-last number
Sn=12n(a+l) Sn = \dfrac{1}{2}n(a+l)

nth term:
a+(n1)da+(n-1)d

arithmetic sequence:
a,a+d,a+2d,a+3d...a+(n1)da, a+d, a+2d, a+3d... a+(n-1)d

To find out if a quadratic can be factorised do:
b24acb^2-4ac if answer=n2n^2 then quadratic could be factorised.

Discriminant:
b24acb^2-4ac

No real roots:
b24ac<0b^2-4ac<0

One real root:
b24ac=0b^2-4ac=0

Two real roots:
b24ac>0b^2-4ac>0

Working out gradient(m):
y2y1/x2x1y2-y1/x2-x1

perpendicular gradient (and gradient of normal):
1/m-1/m

Standard form of straight line:
y=mx+cy=mx+c

To find equation of straight line:
yy1=m(xx1)y-y1=m(x-x1)

For differentiation:
kxnkx^n
Unparseable latex formula:

dy/dx= knx^n^-^1



for integration:
kxnkx^n
Unparseable latex formula:

kx^n^+^1

and divide k by n+1n+1

for working out length:
e.g. AB=root(x2x1)2+(y2y1)2AB=root (x2-x1)^2+(y2-y1)^2

for Area of triangle:
0.5(baseheight)0.5*(base*height)


hope this helps!

Better late than never, yeah, just bare in mind you're not gonna get an A-C unless you're naturally good at maths.
basically all you need to know is;
differentiation
intergration
how to draw all different graphs
inequalities
surds/powers
how to find equations of lines/normals to a curve
arithmetic series or sequences

I think thats about it:tongue: good luck!
Taking this a year early :s-smilie: A Bit scared lol
What kind of marks are u getting?
It would be nice if you said what mark you got for each of the new papers?

i know that the highest grade is a . but what raw mark do you need to get out of 75 to get 90% or over on this ppaper?
The formulae for arithmetic sequences are given in the formula booklet so no need to memorise them.
