i found the max to be 3/2+sqr(27/4)i

I found the max to be: Oops haven't started yet.

how do u meant to do that btw- its not like we can use calculus.

Tut tut.

It's simple parametrics man...

hmmm...i don't think i'll bother.

anyways, i missed out on todays math 1902 lecture at 8am...what did i miss out on- can someone fill me in?

we just continued with the cross products of 2 vectors and just wrote down the properties and we did how the cross products apply to the real world and stuff

omg im stuck on 2 b of the assignment >.< only part left i need to finish ffs

so just tell me which pages in the "vectors" notes (the kopystop ones" should i have read in order for me to understand 2moro's lecture?

btw, 2b is fairly easy, coz what u do is say that the maximum argument is produced when u draw a tangent to the parabola, which goes thru the origin...so find the gradient of that tangent, then u'll c how that tangent actually makes 45 degrees wif the x axis...so yeah, then u can work from there to get the answer for 2b.

ta i knew it was that but dam my friend dam him telling me to sub z = cis@ i was like wtf >.< and tried it and got no where

umm lets see pink book
pages 49 - 54

but some things we did arent in the book, like we did like it was not communative that it was anti communtive or somethng like that so

u cross v = -v cross u and did stuff like distrubative law, multiplying by a scalar like stuff we did for the dot product

okiez- thanks for dat, i'll read those pages....also was there any other thing that u guys can add to the list of what u covered today that isn't in the pink book?

did u try the method that i outlined above?

 

[RZ]

yer don't u assume the tangent to be y = mx since u don't know the point of intersection of the tangent and the curve

yep, and then u solve that simultaneously wif the equation of the parabola...and then u say that discriminant = o....then yeah, work from there.

 

[RZ]

ah got it thanks man, rofl i did like 200 errors with numbers im so retarded damn those long holidays

I met KeyPad today,we're actually in the same Physics prac lol

did u meet him at the math 1902 lecture?? well, if so- sorry i wasn't there man.

(umm... how do i go about 3)b)?)

Euler might help you.

Not the BOS member, the actual guy.

 

[Collin]

Keypad, when are you handing your assignment in tomorrow? I would like to 'check' my answers with you.

 

[KeypadSDM]

Mine's very crap.

My proofs are very very sketchy.

I don't think I'll be topping this course...
