ok
What i do is initially let "Lamda" = 0 to get your first point on the line

which will be (1,0,2)

Next just choose "Lamda" = 1 to get another point on the line. this other point will now be (0,1,4)


Now the point is (-2,2,7)

So let A = (1,0,2) let B = (-2,2,7) and let C = (0,1,4)

so Vector AB = (-3,2,5)
and Vector AC = (-1,1,2)

So Proj(b)A = (-1,1,2)(-3,2,5)/|(-1,1,2|)

So this = 15/(squareroot of 6)

Now length of AB = Squareroot of 38.

so using pythagoras we get

37.5 + x^2 = 38

x= 1/root(2)

isnt the answer ment to be a vector

yeah i thought so.
you know what ?
tutor lol.
he helped me with Q9c lol i tell you truth.

tutor pretty quiet and cool.

lol forget maple, but my answer is different.

project (- 2,2,7) on direction of line x = (1,0,2) + λ (-1,1,2)

direction d is (-1,1,2)

proj_d (- 2,2,7) = (- 2, 2, 7) . (- 1, 1, 2) . d / |d²|

= 2 + 2 + 14 (- 1, 1, 2) / 1 + 1 + 4

= 3 (- 1, 1, 2)

= (- 3, 3, 6)

isnt it what the answer said?

btw cant draw here.

Lol creepy.
he looks like hes up to no good.
like "hey baby wanna make me a gradient to your curve ?"

 

[Omium]

ROFL at the the diagram.

The pic is one post up

LOLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLL

Hmm i was thinking "Pedophile" !!!!!!

My calculus lecturer looks like a hobo on his shot or he's had a party with too many old coots, hags and codgers for one night.
He looks well presented for his lectures though, like a grandpa.

Btw pahor has no photo on the internets but he is a pretty nice old man in his photo at his door

 

[Forbidden.]

LOLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLL

Hmm i was thinking "Pedophile" !!!!!!

cool, sorta looks like a stereotypical professor

lol. could you imagine if you walked past him and he did that smile to you?

Forbid.

Your MATS1101 looks EXTREMELY dodgy and shifty.

This is him
http://www.materials.unsw.edu.au/images/user/profiles/acadstaff/acrosky.jpg

though he looks way more shiftier in real life

 

[Forbidden.]

but that guy should really change his photo.
a pedosmile isnt funny at all, but only marginally funny just to have a chuckle at.
but yeah i thought paedophile.

just make sure the maths men dont see this thread.

but the maths computing labs are gh3y anyway they dont let you access the internets outside unsw

What was the person thinking when they put that photo of him up? :S


Yer, just steal Law computers if your ever lower campus.

Also you can use my username in the chemeng labs. lol sometimes im logged in 6 times at once :S


Oh, and i know a computer that has free internet in the chem eng lab
