Guys I'm in AS and I currently have Physics, Maths, Chem, Biology (Bio is out of idk interest).
I had 7A*s 2As in O levels and had Add maths too.

I want to know if I take Further maths now, at this point in AS (Dec 2014) will I be able to do it and get a good grade? I dream of getting a scholarship abroad, US InshaAllah. (MIT = Dream). I'll be giving SATs next year too iA.

And if yes let me know the books i need for this.
And one more thing, I will have to do Further Maths almost on my own and appear privately so please let me know if this is a good idea.
Help or guidance in any form will be highly appreciated

I am doing F Math privately as well along with Phy, Chem, Math, Eng.
If you have interest in math then go for it.
Its challenging subject, if u love accepting challenges and ace it, then go for it.

For SAT books, look at SAT section on this site.
Good luck.

Question 7 I have just started De Moivre's Theorem and all that, but I can't find any of the identities! Anyone want to explain the whole thing step by step? I will be extremely grateful!

Can someone explain how do I find S-2 in the last part of question 5? Do I need to apply any formula similar as when finding S3?

Too slow guys...I found this: http://mathforum.org/library/drmath/view/70508.html
Now can anyone derive a general formula for the sum of roots to the nth power for quartic equations? I'm working through this as we speak but I am not known for quick calculation.

Thanks for that. So if I'm not mistaken you are using the general formula aS[k] +bS[k-1] + cS[k-2] + dS[k-3] = 0 ? Do you know the general formula for quartic equation?
