    i doubt anything below 75 will get 100 ums, edexcel is a pain in the neck like that
    Yeah Edexcel generally keep the marks required for 100UMS high. Normally it's 75 marks required or sometimes 74 if the paper is harder. This is ignoring what happened with regards to the grade boundaries for the C3 paper last year.

    But that doesn't mean a and b couldn't be fractions

    2tanx -3sinx=0
    2sinx/cosx -3sinx=0
    sinx(2/cosx-3)=0

    sinxx=0 and cosx=2/3

    Therefore, x = 0, -0.84 or 0.84

    Oui Because the answer I replied to is wrong since you can't work out the cos-1 of anything that is greater than 1.
