Oxford Physics Students and Applicants

If you search this forum you might get the answers of a few.
Other wise just say which question it is here, I'm willing to try and give you the answers and I bet most of the applicants are too.

lol thanks a million, but that'd be faraonic, i really intend to do them all eheheh. Did you mean the forum or in this topic?

cheers, David.

For question 1, would it not more mathematically correct to put down +3 and -3?

For 3.i. there's another method of showing it's a right angled triangle by calculating gradients instead, by showing they're perpendicular to each other.

For 4.ii. Could you not say that tan = sin / cos, and that as the angle increases, cos goes to 0. Therefore, tan is always greater than sin?

For 7. Why didn't you use the sum to infinity formula? S = a/(1 - r) ?

Thanks for doing this anyway.

1)no because a square root only gives a positive value by definition

3) yes but Pythagoras is faster and you need it for the next part

4) It's basically the same but yes you could say that as well

7) because it's after the nth bounce not after an infinity of bounces

Really? Never heard that one before.

I cracked off the maths section of the 2006 paper this morning if anyone wants a markscheme (or answer check)

the sample paper or the actual paper ?
cause I've posted the sample paper here already

My maths teacher had to bang that into the head of my whole class because nobody knew of it.
a good example is that square root of x is a function
a function can't have two values for one x
