    i don't get how to find the max and minimum if you work out Rcos(pheta-a) and what the minimum angle can be? please help!

    R is the maximum value, for when that maximum occurs you draw the sin or cos graph and then translate it using the transformation of graphs rules.

    these papers are enrichment material
    (it is a C4 paper)
    Okay so you don't need to know how to create parametric equations??

    Or is that part of the spec?

    it is not part of the spec!

    Please read the instructions carefully at the page on my website (or the thread) about papers S and T.

    Hey guys does anyone know if we have to learn the sec, cosec and cot graphs? I can't imagine a situation where they would help to answer a question seeing as you can convert the three terms into sin cos and tan to get answers to trig questions... Any help would be greatly appreciated!!

    Pretty sure I saw a question asking you to sketch cot/sec/cosec between a set of boundaries once before.

    I think they can ask for sketches of all those graphs. They are possible to work out from the graphs of cos, sin and tan though.

    hey guys wander if someone could help me, basically I need 30 UMS IN C3 to get the grade I need to get into Uni. I know 30 is U and 40 is the lowest graded mark. If I get 30, will it still be counted towards my final score or because it's an E, it will be 0?

    Thanks!

    If you get 5 marks you'll get something like 7ums what ever mark you get it translates to a ums score. Just try your best

    It is often helpful to consider a sketch of the given function - may help you visualise it better

    so for example if you had a function 4-x/2-x how would you find the range

    I've been rather busy with other subjects so I've somewhat neglected maths revision. I was wondering how to use the time left effectively. In regards to content, I'm pretty much confident with most things. As you're familiar with past papers, which years do you think were the most difficult? Also, how do your I.Y.G.B papers compare with the Solomon ones? Thanks for the help!

    I have come across questions like these a few times, how do you find a suitable starting value for an iterative formula ?

    (Solomon paper A - q 8c) Thanks in advancee.

    If you are confident with most topics time is running out so my advice is to start practising with actual papers (open book to start with).
    Only if you have time do practise papers from third parties.

    PS: my personal opinion is that IYGB are roughly as difficult as Solomon ( except some very hard papers and 2 super hard)
