    to calculate R you have to find the area of the trapezium looking shape underneath R, thats bound by the surrounding lines. R= total area unde curve(use limits and integration(-2 and 7))-area of trapezium thing. Now to Find the area of the trapeziumn thing ( as there are no parallel lines in this shape) you have to split it into a trapezium and a right angle triange and find the area of those. Which requires finding the x coordinate where the cubic line crosses the axes. Which requires equating it to 0 and solving which all takes a long time. This is a method that works but takes a while, there could be an easier method. Everyone else in this thread is wrong fyi.

    Okay so I did the 2014 C1 paper about an hour ago and I realised I have absolutely no clue on how to do integration and finding the area under a curve :eek3: would anyone be able to give me the run down? I've attached the question I struggled on, I think its all just knowing where to start, it really got me stumped thank you very much

    How many marks do we get if we just write down the answer and the answer is correct ? Would you still get full marks ?
