Re: HSC 2016 4U Marathon

Yeah, I realised, after checking in wolfram, which I probably should have done before asking.
My bad

For interest's sake, it can be shown to diverge because the summand is on the order of 1/k as k -> oo, and the harmonic series diverges.

Re: HSC 2016 4U Marathon

can someone post some decently hard inequality questions, within the scope of the HSC course (not KOA and paradoxica's "hsc course" level).
Having a boring day at school so i though i might as well do something

Re: HSC 2016 4U Marathon

I'll post a guided olympiad question. Just give me a moment to modify it accordingly.

(Actually, my last inequality posted in the elementary marathon is quite easy if you use the cosine rule )

Thank you very much kind sir

If anyone wants to do that, that's the question that made me rethink all of my life choices during the 4u half yearly

I hate circular motion with a passion

Re: HSC 2016 4U Marathon

Good thing i don't know circular motion yet lol. Did anyone get it in your class?

no everyone just skipped or wrote a few random equations down hahaha

Re: HSC 2016 4U Marathon

That is exactly why I dropped engineering.

I don't have the attention span to resolve and determine all vector forces actingg on the system.

"It's a light rod"

"How light?"

"Massless"

"Well then there is no rod"

"Yes there is because I say there is"

*facepalms*

It was 4u tho, so you could totally get that question yourself

Re: HSC 2016 4U Marathon

They don't usually seem to ask those types of Q's in the HSC (like with a sliding ring), if I recall correctly. I do think they can found in textbook Q's though.

It'd be worse if it weren't massless .

whhhhattt you did engineering? We could've been twins, since no one else in the 2016 cohort seems to do it lol

Elliptic Integrals aren't that bad...

They only require an entire term's worth of content.

Since I dropped, there are 7 people remaining who do it. Such an indivisible number, but my sanity takes priority over convenience of integers

I too enjoy sliding up and down smooth vertical poles and creating lots of tension.

the area in the first quadrant bounded by the curves y = sin x , y = cos x and the y axis, is rotated about the y axis. FInd the volume of the solid formed
