edexcel core 2 exam on 2 june

-pi to pi is just -180 to 180 in degrees.

It helps to know the equivalences

$30^o = \frac{\pi}{6}$


$45^o = \frac{\pi}{4}$


$60^o = \frac{\pi}{3}$


$90^o = \frac{\pi}{2}$


$180^o = \pi$


$270^o = \frac{3\pi}{2}$


$360^o = 2 \pi$

Yup, arc formula, general formula concerning sectors and segments.
Quadratic formula, formula for area of a triangle, proof for geometric series, log laws, formula for gradients and line lengths etc.

I thought we were given geometric series formulae?

also... it isn't explained in this mark scheme, but how do you find the gradient of a radius in a circle.. at a particular point e.g. (6,4). here it's done 4-1/6-2 giving 3/4. but i'm not sure where the 1 and the 2 have come from and why they're being subtracted from the 4 and the 6.

if you're going to use latex, at least figure out the commands

lol mine is 12 oclock c1 ... 1400 c2

XikenElAmo, don't PM people asking us to help you cheat.

It's not on.

lol mine is 12 oclock c1 ... 1400 c2

No way, doesn't that technically mean i could come home after the C1 exam and tell you ALL the answers?!
