    Can anyone tell me how many derivations/relationships are on the higher level course and what they are?

    Take a look at the summary at the end of every chapter. If there any derivations you have to know, they'll be listed. All derivations in the book are to be learned for HL.

    good q, i was gonna ask. i heard these could be quite likely, what with the log tables covering like 60% of the exam:p

    If i head to guess id say 4 or 5, i think we have to know all the ones in the book??

    I hate them sooo much though:mad:

    EDIT: ummtea has it covered above, bad news though :(

    It gets worse, the end of chapter summary doesn't mention some derivations that have been asked before. e.g.

    1. (Refractive Index Between Two Media) aNg = 1/gNa

    2. (Refractive Index With Critical Angle) n= 1/SinC

    I heard there's like 11 that can come up but I just ahve no idea what they all are...I know a few like newtons 2nd law,period of orbit,linear and angular velocity but I just want to make sure I don't leave any out becaue I'm guessing there's gonna be a few on this year due to the log tables.I know one or two are off cause they came up last year.......looks like I'll just have to do some research through past papers and see what has come up.I'll post them later.

    Just found this.Someone posted it a while ago.

    v = u + at

    s = ut + 0.5at^2

    v^2 = u^2 + 2as

    F = ma

    v= wr

    T^2 = (4.pi^2.r^3)/GM

    n.lambda = dsinO

    R = R_1 + R_2 (resistors in series)

    1/R = 1/R_1 + 1/R_2 (resistors in parallel)

    F = qvB

    This is a link to the Physics syllabus. Check it out from page 56 on the PDF file, actually page 52 of the syllabus.

    Note, there are no derivations required at Ordinary Level.

    All the required equations are listed here and the derivations are marked with a 'sword' symbol. Look out for the symbol on both sides of the page - some are beside the equations and some are beside the name of the quantity.

    I haven't counted them, but there aren't that many - at least not near as many as there used to be!

    It could be useful to print out the equations and use them for revision.
