goodnight yall
OpenStudy (danjs):
Ill do it at work when i am bored tomorrow , and scan in the page, to the thread tomorrow
OpenStudy (hba):
Btw i got AB as <2,2,-2> and M as <2,1,-2>, AC as <3,-3,3>
OpenStudy (jhannybean):
I cant visualize it -.-

Wouldn't AB be a line segment? So you're translating it to the original and then writing it as vector?
OpenStudy (anonymous):
I would say \[
M = \frac{A+B}{2}
\]
OpenStudy (hba):
That's what i did
OpenStudy (anonymous):
I would say that: \[
A-N = 2(N-C)\implies A+2C = 3N \implies N=\frac{A+2C}{3}
\]
OpenStudy (hba):
N=<3,-1,5/3>

Mid point is like an average. For N, we're talking a waited average.
Hmmm, let me try a drawing though.

\[
M = A+\frac{B-A}{2} = \frac{A+B}{2}
\]
OpenStudy (hba):
It says AN=2NC ?
OpenStudy (hba):
You took A-N=2(N-C)?
OpenStudy (anonymous):
Hold on
