如果你全部都不明白的话....
我想...你需要的是找个tutor从头说起...

O A
C
B
D E
(a) Express the vector O􀀀􀀀!E as a linear combination of O􀀀!A, O􀀀􀀀!B and O􀀀!C.
(b) Let A = (2; 2; 5), B = (􀀀4; 3; 1) and C = (2;􀀀1; 1). Find O􀀀􀀀!E and jO􀀀􀀀!Ej.
(c) Let A = (􀀀2; 0; 0), B = (􀀀k; 3; 0) and C = (0; k; 1), for some k 2 R.
(i) For which values of k is the equation jO􀀀!Aj2 + jO􀀀􀀀!Bj2 + jO􀀀!Cj2 = jO􀀀􀀀!Ej2 satised?
(ii) Sketch the vectors O􀀀!A, O􀀀􀀀!B and O􀀀!C for the value(s) of k you just computed. What
are the angles between them?
(d) In general, when is the equation jO􀀀!Aj2 +jO􀀀􀀀!Bj2 +jO􀀀!Cj2 =

I know which problem you're talking about unfortunately since I don't have the assignment I can't quite remember it, and I'm having trouble reading the one you posted.

It will be helpful for  ...

I'll post the 108 assignment here for you.

I think he wants help with Question 9
