Ask Omed62.

Hi spiral, can you tell me what you are doing at uni :)

Yeah, I heard if you have done 4U maths and physics you can pretty much sleep in first semester engineering :3

Even if it was accurate, concepts in 3u and 4u are not difficult to understand, applying them can be difficult.

Just get a terry lee 3u textbook because it has full solutions and do chapters 1-5 then 9-12. If you need a tutor then get someone who charges around $15, not worth paying more :)

Re: Experienced & Affordable Eng Adv(96) tutoring + FREE Notes Bump!

elementary functions, differentiation, basic integration techniques and coordinate geometry in three dimensions. EZ :)

Re: HSC 2013 4U Marathon What is the fastest way to prove the AM:GM inequality? My teacher uses induction + calculus which is a tedious method.

You will find it extremely difficult.

Because 4U Cambridge is a terrible book! It only covers the basics of MX2. Bill Pender's is awesome!

Re: HSC 2013 4U Marathon The only geometric series I can think of are: (e^{2ix})^1 + (e^{2ix})^2 + \cdots + (e^{2ix})^n and (cis2x)+(cis2x)^2+...+(cis2x)^n By the way, do we have to memorise the sums to products formulas? I have seen many questions that require them but I think they give the...

Re: HSC 2013 4U Marathon I got this: \int_{0}^{\frac{\pi }{2}}\frac{e^{i(2n+1)x}-e^{-i(2n+1)x}}{e^{ix}-e^{-ix}}dx which doesn't look easier then the original lol :(

I don't get why he use ellipsis in almost every sentence and I don't get how it is possible for someone not to be able to construct a single logical sentence. I mean what is this: "share you results and ranks bro... I am ranking in the top 10 for everything". No body cares, you study for your...

Can't you just not use the bold parts? That way we won't know it is you. Simple.

Wow, these are your ranks at JRAHS! You must be very intelligent, Mr. Omed62.

hi Omed. At least try to change the way you write... or is that too difficult for you?

Are you who I think you are?

For 95 you need around 75-80 raw marks I think. Post your questions about english in the english forum.
