    Where exactly in France? I would presume Paris. :pierre:
    Paris would be nice, I've never been to France before. Anywhere is fine (within reason )

    Ugh, whenever I do some impossible Maths stuff, then I get to the end of the equation and then I somehow fail to realise a positive number turns negative on the other side of the equation... :facepalm:

    You need to turn this:
    3Sin(2x) = 4Sin^2(x) - 2Cos(2x)

    Into this:
    4Cos(2x) + 3Sin(2x) = 2

    You have 3Sin(2x)

    So you need to turn:

    4Sin^2(x) - 2Cos(2x) ---> 2 - 4Cos(2x)

    Sin^2(x) = (1-2Cos(2x))/2

    Does that help?

    It took me 5 minutes to understand where you got
    (1-2Cos(2x))/2
    From but I get it now you just ha to rearrange

    Cos2A=1-2sin^2A

    :facepalm:

    Thanks though:hugs:
