# Edexcel A2 C4 Mathematics June 2015 - Official Thread Watch

1. Can you guys help me with a Q?

It's practice paper A2 for C4

This is the question

I'm stuck on d) :P

I got this:

H=A^2/4
H=0.25

Can anyone explain? :P

I personally find vectors to be okay. I don't find it too difficult or too easy. How's your prep going for C4 anyways?

Also, try question 6D from AQA Maths June 2013 C4. It's one of those 'difficult' vectors questions. :P
Thanks for the question! I'll try it out now

If you have anymore of the harder ones please let me know xD

i can usually do most of them but the last part of the question i usually drop half of the marks, its 2 or 3 most of the time but still
Yeah that sometimes catches me out! Just draw a diagram and that usually helps!

What's is the time found in part c? Half that time and plug it back into the formulae for h.

1/(1/5 - (root1/2)/5)

When plugged in formula for h I got something like 56.7 and so on

Any other ideas?

You got the answer but I don't think that's how you work it out xD

Idk what you did but the answer wasn't rounded to 0.25, it was 0.25 exactly.

Oh and you got b) wrong at the end

root(pi)(r^2) doesn't cancel with (pi)(r^2)

It instead becomes a new expression of k.
12. I've finished all the past papers, what shall I do next?

Solomon, Elmwood, or Delphis papers? Which one is the best series/most helpful?

Many thanks!
13. Im pretty sure it doesnt matter how you work it out, as long as you get the right answer at the end

For b) if you rearrange for h, then you could put it in the form of (A-Bt)^2

And loool thanks

Good ol' cheeky Nandos!

Haha, thanks. Have you tried the elmwood/delphis papers? Not sure if they are worth doing

I have looked at them and solomons ar eharder id say tbh solomons arent as useful as they were in C1/2 where they were really good. But if you have done all the papers (kudos as ive only done like 3 lol I dont plan on doin any more) go for solomon and do the IGYB papers.
