    Are C3/C4 solomon papers harder then the normal exams? Or easier?
    Do the normal papers and you will find that there are only around 2 questions which are really challenging.

    On the Solomon Press all of them are normally challenging, so it's really easy to find your weaknesses, which should really be the whole point your revising.

    I'm going through as many Solomon Press as I can in the next 2 weeks (timed) , then starting normal Papers after.

    I'd say some are on par, they just make you think abit more about what you're doing instead of following certain routine like you normally would.

    With a name like MathsNerd you must be a god of maths.

    I find the Solomon Press much more challenging.

    Try to ignore my username as its completely inaccurate, it was just the first thing that came to my mind when it asked for a username, it's sad I know

    Well for C4 I've only done about 4-5 of them but they really don't seem much harder than what I was given in lesson, although I self taught C4 because my class was going incredibly slow, the integration is the main part really and normally contains to majority of the marks in the exam so make sure that's as strong as possible.

    hey guys i got a question about C4. I was doing EX 6E in the new edexcel book page 100. I've been told this is integration by recognition however a couple of people have told me to learn integration by substitution first and then use this exercise as practise? Is this is a good idea? The examples before the exercise seem to use a weird method... Please help
    Thanks

    Have a look in your formula booklet and you should recognise how to change that into something you can integrate.

    cos(3x+2x)=cos3xcos2x-sin3xsin2x
    cos(3x-2x)=cos3xcos2x+sin3xsin2x
    subtracting gives....

    There's an example of this in the textbook try example 6 on page 93. Do that example and then you'll be able to solve this one!

    Is it differentiation? You'll have to post it. I don't have the boom infront of me

    Yeah, I started them a couple of weeks ago (c4 papers), although i've only done about two papers. Vectors are the most difficult topic for me.
    What have you been getting so far?

    I haven't really been doing them properly under exam conditions. I've been doing a question, looking at the answer and correcting it if the answer is wrong. But I think i'm probably averaging around the 67/68 mark. Although a lot of those marks are from numerical errors (e.g. substituting in limits incorrectly).

    well i'll write up the whole question since you will probably need it:

    12) Referred to a fixed origin O, the points A,B and C have position vectors (9,-2,1), (6,2,6) and (3,p,q) respectively, where p and q are constants.

    a) find, in vector form, an equation of the line L which passes through A and B. (answer - r = (9,-2,1) + t(-3,4,5).

    b) Find the value of p and the value of q. (answer - p=6, q=11).

    c) Calculate, in degrees, the acute angle between OC and AB. (answer - 39.8 degrees).

    d) The point D lies on AB and is such that OD is perpendicular to AB. Find the position vector of D. ??????????!!!!!!!! :confused:
