Yes, it's a very broad question. Thanks.

There is no part i involved. It is just on its own

At once? So for the k+1 step, after subbing it in, what to do next?

Sorry, i didn't mention it. Yes.

1. Define the process of globalisation and explain how it has affected people's lives For the bolded part, what do I talk about? Does this include the main indicators of globalisation, such as: *Financial, trade and investment flows *Movement of workers between nations *Technology...

Hello, I have come across this question, and don't know where to start: - Prove that for any natural number n, 2(√(n-1)-1) < 1+ 1/√2 +...+ 1/√n < 2√n http://imgur.com/jif1ZMR for an inequality like this, what is the best approach? For the k+1 step, i'm assuming bringing them all to a single...

For proving inequalities by induction, at what point can you finally say that the statement is true? For example, for the question 1 + 1/2 + 1/3 + ... + 1/n < √(n), for n >= 7 I proved true for n = 7, then assumed n = k but for proving true for n = k+1, what exactly do I have to do...

tempting...

Thanks enigma. Btw, the reason why you started with n = 3 was so that they don't become 0?

Prove by induction that the sum of the angles of a polygon with n sides is n-2 straight angles. I don't know how to express this into an equation.

yes, that's what i'm talking about.

Yeah, I might buy it, or make it myself

Are there currently any HSC Physics by topic documents in existence? The one on the thread currently sticked on this forum was apparently removed. If not, I can make and post a new version

It has become increasingly apparent to me that accelerants generally do better than normal math students. So, I thought that learning content at an earlier stage would allow more time for concepts to sink in, thus, leading to a better outcome. my question is: What is better? - Learning...

X.X Have to take a break when that happens..

I have another question that leads on from this one. Deduce that if alpha is a none real root of ax^2 + bx + c =0, where a,b,c are real, then the conjugate of alpha is the other root of this quadratic equation. I don't really understand this question. Any explanation is appreciated,

Oh cool! For each step, do you need to state what theorem you are using?

Thanks, but i'm slightly confused about the working out. The worked solution shows the conjugate of the entire equation, then slowly working down to the conjugate of alpha only, thus the conjugate of alpha is a root. Is this essentially what you are doing in your proof? Also, do you need to...

"If α, where α is a non-real complex number, is a root of the equation ax^2 + bx + c = 0, where a,b and c are real, prove that its conjugate (conjugate of α) is also a root." Can someone please explain to me step by step how to solve the q
