Yep, although many places schools will have to order exams for students who wish to take them.

Thanks! I'll have to order it from Amazon:smile:

I have studied physics and quite a bit of physics in calculus, but I need to know what to study (I guess you could say revise) in this book when preparing for these exams:wink:

Hi, When I am using Principles of Physics by Walker, Halliday, and Resnick to study for AP physics 1 and 2 exams, what chapters/subject areas should I focus on to get at least grade 3? Due to a lack of time to study I will need to study what's most important. Alternatively, recommendations for...

Oh okay! Thank you :smile:

A lot easier to follow that direction, thanks! The final step has 2n and 2n - 1 instead of (-2)n and (-2)n - 1 which I don't get.

Homework Statement Homework Equations The Attempt at a Solution I don't get how they got what's stated in the above picture. Where does 1/2 and n/(n + 1) come from? Can't you just show that an + 1 ≤ an?

Yes I made an edit on my post, I was thinking of u'/ln u. I think I've got it now.

Wouldn't that be e-x ln 2?

∫(1/2x) dx = ∫(1/ex ln 2) dx u = ln 2 x → du = ln 2 dx 1/ln 2 ∫ du/eu = ln eu / ln 2 = ln ex ln 2 / ln 2 = x ln 2/ln2 = x Okay, what did I do wrong?o_O Edit: I was thinking of u'/ln u, my bad! 1/ln 2 ∫ e-u du = -e-u/ln 2 = -e-x ln 2/ln 2 = -2-x/ln2 Is this correct?

Homework Statement ∫1∞ 1/2x Homework Equations 2-x = (eln 2)-x Could possibly be relevant, I don't know. The Attempt at a Solution y = 2-x ln y = -x ln 2 1/y dy/dx = -ln 2 -x/2 ...

You are fantastic, thank you so much for this!

Thank you, the link was very helpful. Maybe the Norwegian equivalent of UCAS is a little confused cause I am... It says (translated): From 2015/16 2 AS-levels will no longer replace 1 A-level. The combination 1 A-level and 2 AS-levels will not give a [Norwegian equivalent of the GCE] and the...

Thanks! It also says I don't need the GCSE, what does that mean? When taking the A-levels, do I need to take the AS and A2? :-)

Hi! What does the General Certificate of Education (?) in the UK involve? Is it the same as A-levels? Edit: It says I need the GCE with two A-levels, what does this mean?
