so.. ND, you're last in the class. shame

there's a better proof in teh arnold book, page 242 example 8

Your maths teacher is the most useful resource, plague him/her with questions

think I got what maniacguy has in mind scrap the calculus part @ = Arc AB centered at Z > AB

let's just hope everything goes smoothly then :D

haven't had any, unless dad counts.. and that was fews years ago. never knew turtle tutored, must be very interesting.

bashed it , can't find an elegant solution consider the points Z, A=(Z-1), and a point B on the line OZ where ZB = 1 and Z is not between O an B. If OB < OA let C be a point on OA such that OC = OB (case 1) else let C be a point on OB such that OC = OA (case 2) now, OA represents...

1) x+y=1 x,y E R+ m,n E N prove (1-y^m)^n + (1-x^n)^m >= 1 2) given m colours to paint the vertices of an octohedron, find the number of possible different octohedrons, a colour can be used up to 6 times.

EDIT:Never mind, was half asleep when I did the question.

I second that.

Was flipping through books today: Looks like your teachers have been ripping questions straight off textbooks Arnold page 252 exercise 8.3 question 9

excuse my ignorance.. I don't see how that's correct. ____________________________ Fosweb: see if this helps: prove (a/b + b/c) + (c/d + d/a) >= 4 you will use the given result 2 times exactly

hm...

also, your units.... what units of time are you using? seconds? mins? hours? EDIT: I see, but it would be easier if you used a unit of time instead of the angle directly

Hint: you're maximizing speed, not distance.

Underthesun: expand and collect terms, see what you get. read the question carefully, and think about what you are maximizing.

EDIT: was asleep

"general math rocks" -> non sequitur

mcgrady, what was the point you were trying to establish? hard work pays off Did U Know For general maths.. percentile) ur makr of 82 because UAI equiv = 68.... if u had a top 1% mark (99th percentile) ur mark of 92 became a UAI equivalent of 80... if you had a top 10% mark...

what about 0th/0
