check your final line, beta=pi/2-2*alpha not pi/2-alpha

a/b=sin(alpha)/cos(2*alpha) *

^ He's a pretty cool dude

have you told your parents about the fine yet (lol)?

damn so tired...'twas a good day!

Prairiewood

damn, okay thanks for that. awaiting carrot's help for now.

lol rep system is gone m8 a) v^2=u^2+2as Since u=0, a=g, => v^2=2gs When s=50. => v^2=100g=1000 taking g=10 m/s^2 Hence, the velocity of the man at the end of free fall is roughly sqrt(1000) m/s b) v^2=u^2+2as (Note that I will changing the reference point to where the rope reaches natural...

I'm going to be catching the T80 bus to Parra. Just to be sure I want to ask does the T80 ALWAYS stop at this side of the station (refer to attachment)?

^ hahhaahahahahaha

Re: 2012 Year 9 &10 Mathematics Marathon Weren't you interested in the more stimulating problems? I know I was.

Re: 2012 Year 9 &10 Mathematics Marathon I just tried it and got 1/x

Re: 2012 Year 9 &10 Mathematics Marathon yep, well done :)

Re: 2012 Year 9 &10 Mathematics Marathon yep, that's what I got.

Re: 2012 Year 9 &10 Mathematics Marathon Good question.

Re: 2012 Year 9 &10 Mathematics Marathon yep simplifying leads to the general equation of an ellipse x^2/a^2 + y^2/b^2=1

Re: 2012 Year 9 &10 Mathematics Marathon the question is basically asking for the maximum amount of mushrooms you can store in the standard case. you assume that each case is used to this maximum.

This.

I remember doing this a while ago now. k=2/3

Is it sqrt(3)?
