Elementary math

its just pythagoras in disguise, do you have a problem with pythagoras?

>>8975161
Wouldn't it say "|r|" or something then. because you get the hypotenuse not the whole nummber

>>8975164
PS

|Z|=sqrt(z^2) = sqrt((a+bi)^2)
not
sqrt(a^2+b^2)

>>8975167
you serious right now? how about you look this shit up for yourself, it's right there on wikipedia.

so what, just define a new norm that you do like,

>>8975200
I like your thinking.

Something like:

|z|=|a+bi|
{
if a<0 and b>0: |z|=-a+bi
if a<0 and b<0: |z|=-a-bi
if a>0 and b>0: |z|=a+bi
if a>0 and b<0: |z|=-a-bi
}

i would consider much more logical

>>8975209
whops

if a>0 and b<0: |z|=a-bi
not
if a>0 and b<0: |z|=-a-bi

>defining the norm as a complex number

There is a difference between a norm and the absolute value function.

>>8975215
I thought it was the other type of norm

>>8975217
I don't know what "other type of norm" you are talking about. But a norm isn't a function that makes a number positive. It gives an indication of size. Complex numbers are just vectors, and the most obvious function to find the length of a vector is just to find the actual length with pythagoras.

Saying that the length of (1, 2) is (1, 2) makes no sense at all.

>>8975160
This is probably the most retarded thread on /sci/ right now. Have you even taken complex analysis brainlet?

>>8975209
Why write it like such an autist? |z|=|a|+i|b|

So instead of defining a norm that gives you an actual scalar indicative of size, you prefer something that just moves your complex number into the first quadrant....
