    For clarity. Numerical/graphical methods does not refer to cast or using graphs to generate other solutions. Graphical means you plot a graph e.g. if sin x =1/2 and you drew the line y=1/2 and the sine graph and then read off the intersections. Numerical means you used a method like newton rhapson or trial and error to find the solutions

    Thank you.
    Yes you can use them. Arsey has essentially used a graph to generate the other solutions he's just done it the quick way

    Same. I am just so used to drawing a sketch of the graph and working it out that way. The cast method gets confusing if you are looking for values beyond 360 degrees.
    You can still use the graph as long as you show you working out as well, that message only means that you cant use trial and error or just draw a graph and show the values...if you get what I mean, I've even started to confuse myself too now!

    This is on the official edexcel site about c1 paper leak, why not about c2? Is it because they don't know or because it's a lie?
    I hope no one has an advantage of seeing any leaked papers, so unfair
    The papers weren't even leaked, just some dumb kid deciding to take his/her mobile phone out in an exam.

    I highly doubt anyone actually has the C2 papers also.

    You keep saying R/IAL but can you give me a link of where i can find these questions?
    Sorry! I didn't know people were confused :/

    http://www.physicsandmathstutor.com/...rs/c2-edexcel/

    Scroll down, there will be June 2013/14 IAL/R papers so that's 4 more papers to do. They're usually harder so don't worry too much if you get a bit under your usual marks.

    Thank you. I guess I kind of just panicked.
    Good luck for tomorrow.

    Wouldn't you use the formula Arc length=r(theta)
    So that would be 7x0.8
    Make sure your calcs in radians

    Guys, tbh I don't think the C2 paper was leaked. People on twitter have been calling up Edexcel and they've confirmed it isn't. I'm sure it's just a rumour
