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

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)

projd (- 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.

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.

a pedosmile isnt funny at all, but only marginally funny just to have a chuckle at.

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
