Re: Discrete Maths Sem 2 2016 Okay figured it out: - First we check if the graph exists by checking if all the degrees of each vertex sum to an even number. - We then follow RealiseNothing's approach. - We take note that if the vertex with highest degree is equal to or greater than the...

Re: Discrete Maths Sem 2 2016 Not too sure. Haven't even tried any questions about it yet.

Re: Discrete Maths Sem 2 2016 My tutor said something along the lines of : No simple graph if biggest vertex degree >= # vertices or or something like that. Not too sure havn't tried it out yet.

Re: Discrete Maths Sem 2 2016 What's the point of doing all this when you can just use the handshaking theorem at the beginning to see if the graph exists?

Re: UNSW chit chat thread 2016 I understand the written part of the coding exam but the actual coding isn't pointless...

You're fun at parties...

$ If $ a \cong b $ (mod m) $ then gcd(a,m) = gcd(b,m)

$ Prove if true or give a counter example if false: $ $ For all sets A, B and C, $ A \times (B \cup C) = (A \times B) \cup (A \times C) lel LaTeX isn't working.

R.I.P to the people who think they can actually sell something on this site.

I think LaTeX is screwing up today...

Thanks mainly Integrand for saving me from dropping out of my degree by helping me in maths 1B but I need everyone's help just a bit longer for discrete maths. $ 1) For B $ = $ { $ \varnothing,0,{1} $ } , are the following statements true or false? $ a) \varnothing \subset $ B. Why ?$...

What I wrote was what the queation gave

Wrote the question wrong ahah :'(

Okay it appears I may have read the question wrong : $ Let $ p_n $ for $ n \geq 2 $ denote the number of integers less than or equal to n that are prime. Do either of the series $ \sum_{n=3}^{\infty}{\frac{1}{p_n}} $ and $ \sum_{n=3}^{\infty}{(-1)^n\frac{1}{p_n}} $ converge? $

I had like a few seconds so i just checked it with the harmonic series without checking the inequality sign... R.I.P

Thanks guys just a question from the exam: $ Suppose $ p_n $ denotes the nth prime number. $ $ Do either of the series $ \sum_{n=3}^{\infty}{\frac{1}{p_n}} $ and $ \sum_{n=3}^{\infty}{(-1)^n\frac{1}{p_n}} I said the first one diverges by comparison test and by Leibniz test the second one...

Re: HSC 4U Integration Marathon 2017 1 Paradoxica is enough tyvm.

Re: HSC 4U Integration Marathon 2017 Dividing by tan^2 is something you pretty much only see in the marathons. Can see you've been working hard keep going.

We roll a die successively until we roll six consecutive 6's, in which case we stop. a) What is the probability that we stop after the thirteenth throw? b) What is the probability that we roll the die at least 10 times?
