    Doing june 07 OCR maths worksheet

    in question 6)i)

    I got 3e^(2a) + a^(2)/2 -3 = 42

    I need to simplify this to get..

    a= [ln(15-a^(2)/6)]/2

    [ ] are just secondary brackets

    add 3
    subtract 1/2a2
    divide by 3
    take logs
    divide by 2
    take the 1/2 up the log
    ....

    is this any good?

    When doing questions like this you need to work backwards in your head and undo the form they give it to you in, if you do then the steps to rearrange it into that form are obvious.
