What math class would a problem like this appear in?

You appear to be claiming that |-i|=i. Why?

ofek :
but it’s ln(abs(i)) and since abs(i)=1 wouldn’t the ln be 0?

laze :
isnt |i| = 1 => ln|i| = ln(1) = 0

Salt no limit :
Isn’t it just arctan1 - arctan0 ?

Ive never thought of trying to solve this integral this way i always go to residue theorem this is amazing.

Zilyph :
Given that you’re integrating over the complex plane now ln is defined for negative numbers so shouldn’t you not use the absolute value when integrating, this also gives the correct answer

why not just do trig sub?

Can you solve this?

vagoberto :
beautiful! but at some point (near the end) you just forgot to take the absolute values ln|i| and the answer would be different.

why not write x² + 1 = x² - [e^(iπ/2)]²
