L=sqrt(|x1-x2|²+(i|y1-y2|)²)=sqrt(|x1-x2|²-|y1-y2|²)]]>

So for example, if you had a vector <1+i, i-1>, the absolute value of your x component is sqrt(2), the absolute value of your y component is sqrt(2), and so the length of the vector is 2.

The answer is {

`[i]italic[/i]`

If I tell you it won't be interesting

]]>it by :italic(i)]]>

**v**=a**i**+b**j**

(here **i** is vector, not (-1)^(1/2)! (-1)^(1/2) must be italic *i*)

What is the coordinate system?]]>
