    I'm doing the mixed exercies now and thats what I'm stuck on and its annoying me as a few weeks back I would have probably figured it out. Im going to wtach vectors videos on examsolutions and then Ill post it on here if I still need help. Its an easy question I can tell, I just cant remember what to do.
    Go back and find similar examples. All problems are pretty much pythagoras and dot product.

    Personally I would say don't waste your time with the book. Though it is an excellent resource for other topics in c4 particularly integration I don't think It is useful at all for vectors. Instead I would recommend the pack of vector questions that you can find on physics andmathstutor's website.

    Yeah loads of people just stick to those mixed exercises. Starting papers is best as there are about 10 years worth of edexcel ones and also Solomon ones

    Hmm. Id say do those review exercises first as I did them first and then had mocks and got 100 100 in C3/4. The review exercises are from pst papers.

    How do you do 4d? I don't think I understand how we use point coordinates of D we found in the previous part.

    I am on my way home. I am going to have to do the question fully to have an idea of what is going on but have you drawn a diagram?

    Make one if you want to. None of these are actually "official" anyway - it's just the thread starters (probably other students) decided to put the word "official" in the title to make it look more fancy.

    lol i am aware... i just call it official because as the exam nears multiple students tend to create multiple threads so finding the original (official) one is a task.

    Question about Solomon papers. How much more difficult are they compared to normal papers, like what's a good score. Also do they get progressively harder from Solomon A to whatever the last solomon paper is?

    To answer your first question,
    It all depends on the year, last year I did no solomons for C1, turned out to be an easy paper and I just missed full UMS (by 2 raw marks)

    If I did solomons, and it was a hard paper and it helped then thats another story, so you cant really compare but generally solomons are harder than the usual edexcel papers.

    Integration is all about practice. Questions will only get that knowledge back. Do a paper a day until the exam and it will stick as I wouldnt risk relearninng it now then leaving it till june to revise as the same thing will happen.

    (1+cos2x)/2 is a single trig function ......... Think of double angle formulae
