Re: 2012 HSC MX2 Marathon

I don't want to spoil the party but...

Any chance we could have questions more orientated towards a regular MX2 student, or a little harder, but something that most should at least be able to attempt. A lot of people would probably be scared off, especially since you guys are into or out of uni maths already!

Should start at thread just for them elsewhere lol.

Umm no, largarithmic is correct...the integral does not converge. The hypotheses of L'Hospitals rule are not even satisfied here.

yes, i simplied expression in terms of sin and cos, and got it down to ln|1/(1-sind)| so yes it diverges

Re: 2012 HSC MX2 Marathon

Something I predict will appear in either the school Trials or the Complex Number exam term test (verified appeared in already 3 schools as per my prediction last year haha):

Find the value of:



OR

Find the value of:



Even better:

come on so boring, (1) 2012 divisbe by 4 so 1, (2) collasping sum so boring, (3) AP with powers once you multiply them all.

I hope schools can take these and make them harder.

Combining these or putting in terms on n is a much better example as they would have to consider odd and even case

Haha, the first one actually appeared in 3 school #1 assessment tasks already. Too predictable.

Eugh Maccas fries.

Re: 2012 HSC MX2 Marathon

Shoe string fries. Perhaps you might want to stack them up and rotate it about the line y=4...

Maccas makes Spiral fat...

Re: 2012 HSC MX2 Marathon

you're not the only one, it does that for all, however, how do robots gain weight by means of human food?
I thought eating metal would make you gain weight

Re: 2012 HSC MX2 Marathon

I eat nuts and bolts and humans.

I better go study or clown will eat me, I will revisit the conics question I posted up, I think it's incorrect.

Post more questions, when I get back tomorrow I shall be having fun on BOS...

your conics question is not entirely wrong, the m<0 condition restricts point of contact to quad1 only, so if you lift that conditon the question is fine

Yeah that's probably a good idea. This one is for people who are doing their HSC, and not done it already,

Are you sure this is right, it looks like RHS should be equal to -1*LHS
