    Well, I'm 80% sure the answer is 5. I differentiated the equation and got 5. double checked it as well.

    Yep, it was either X=1/3 or - 1/3, can't remember exactly.


    I think it was - 1/3 because it'd instantly prove that you cant have a negative value for the x-coordinate.


    Ah well...

    Yes, I would agree. Although what confused me was that there was two tuning points?? or was there just one point of inflection?

    The Edexcel paper was soooooooooooooooooooooooooooo easy!

    I can't believe that's two thirds over and done with, both papers were really nice. I think todays paper was even easier than M1 - what do you think?
