# Math Help - question on complex nos.

1. ## question on complex nos.

hi... there has been a question which always crosses my mind whenever i see complex numbers...
we say..
|x| is defined as squareroot(x^2)
so,
why do we not write |i| as i... (squareroot(i^2)=i)? (note that 'i' means iota)
now u'll say that modulus function has also been defined as distance of the argument(i, in this case) from the origin..., which u say is i unit from the origin.. but why can't be the distance of a point from the origin be 'i'(iota) units ???? whats wrong with it ???

let me frame an example here..
u draw a graph with Y-axis scale as i unit = 3... then in reference to this graph, do we write |3|=1 (as distance from origin=1 unit) ????? the answer is a no.... then why cant we treat iota in the same way?? here also we are defining 1 unit of y-axis as 'i'....

Do not post the same question twice under any circumstances.

This is the third time. You can be banned from this sight if it happens again.
