In reply to Maksim Volf. First of all when i is an imaginary number or complex number or unreal number because i=√-1 And that's why it is when i.i=i^2=-1

You are talking about complex, not vector, i. e. i = sqrt(-1).
As such isqr = -1

In reply to Maksim Volf.

ixi=0 ; here our ” i ” is a unit vector.
i² = -1 ; here our ” i ” is an imaginary number.

In reply to Maksim Volf. well the i that u are talking about is imaginary no which is root (-1) here i is aunit vector we are talking about.just same symbols used for different things

In reply to Maksim Volf. There, i is an imaginary number which is the root of -1. So, i*i=-1.
