1/u = x Limits become, 0 and Infinity I u^2/(u^4 + 1) du Limits( Infinity & 0) I = 1/2Arctan(u^2) * u - I 2I = Infinity I = Infinity EDIT: Are we allowed to use the hint? Partial Fractions become very difficult but eventually yield the same answer.

L(x) = f(a) + (x-a)f'(x) L(x) = -xSinx + aSinx + Cosa I guess you could expand sin and cos from here.

NewEgg would get it first I would have thought, I am just curious about the price.

Quit while your ahead, CS is a waste of time.

Any idea when it'll be available on NewEgg?

And all of us have FX-60s. I reckon the next series of Motherboards will have to have double socket size to account for the gigantic fans.

Ok, For the first question. E: x^2/16 + y^2/9 = 1 Tangents are drawn from P(3, 4) If you substitute x=3, you will get two answers. Same for y, Find the gradient and then the first questions done. (Two points is probably the only way) Didn't come out either. The second, Didn't come out...

The conics question is simple, just sub in either the X or Y value and solve the Quadratic. The differentiation, Do you know implicit differentiation? The graphs, that just means that the graph is half as wide as before.

There is no way that you can 'understand' string theory without knowing the maths behind it. There is a pretty general description on Wikipedia, however if you are really interested buy a intro to String Theory book from Amazon.

Well they do have 1KW Power supplies...

Q3 Just sub in ki for z. To get K= 1. Then just factorise(Over C) to get the roots.

I like Maths, I like thinking, thus I chose to do Extension 2 Mathematics.

Interesting, is it worth considering limits?

Arctan (sinx) + C
