It's called i! i! It's fucking awesome! You can like do loads of shit with i!!! You can totally work out complex trigonometric function with fucking i! i's the shit bra! Some dude named Euler was totally fantasising about i and then he was like, "Dudes! I should, like, totally do something with i!" And he made an equation and BOOM! We now know the equation for oscillators with viscous damping....and, well most other things too since Euler's equation helped trig generally....But fuck yeah oscillations!

I'm not saying you don't know what it is but I am saying you are not thinking about how awesome it is! I mean...whoa! It's got like it's own letter and everything! Not just any letter....but i! as in, "i own dis shit!" It's magical!

You do realize that they use any letter for the square root of negative 1 right? In electrical they use k.

domain: x</=0

You're talking about imaginary numbers. They're real... Wait, is that a paradox? Anyway, they fall in the category of complex numbers... I think.

its is +/- radical 1 bro

*radical x

there are no two negative numbers that multiply to be a negative. You can not take the square root of a negative without it resulting in an imaginary number.

imaginary numbers. you can only graph in an imaginary system, and then since everything is imaginary, you have nothing.

No if x happened to be negative 4 for example, then y would be 2. (- -4)^(1/2) is the same thing as (4)^1/2

u can graph any real number on an "imaginary system" (argand diagram) it just has an imaginary component of 0, but this is unecessary. If x were -1, then the equation y = sqrt(-x) would be sqrt(1) = 1, which is quite real

Which are a part of numbers nowadays, its categorizes itself under complex numbers.

They are IMAGINARY. you NEVER USE THEM IN REAL LIFE. You give me one real life situation where I will use these numbers.

physics and engineering, specifically electrical engineering

maybe in theoretical physics, but in applied physics, you'll probably never have an imaginary anything. because you're APPLYING it

complex numbers are used with currents in electricity

I can't, and yes they are imaginary, but they are a part of our number system, like it or not.

forgot the i

yes but what two numbers multiplied give a negative number?

its (-x)^1/2

It must be the same number, and both numbers must be either negative or positive. So no, you can't.
1*1=1
-1*-1=1

thank you for being intelligent.

1/-x I believe.

I mean -x^1/2

Overlooking your terribad syntax, its infinity (im not asian)

True, I should have said as x approaches zero, not limit as x approaches zero.

The ways in which the person's arms are bent is how the graph of the functions below it look. The one with "crap" just means you fucked up.

I'm so asian...

I appreciate the explanation, but I'm going to go sit in a corner now.... and just ponder

domain= x</=0

Actually, that does make sense. Was thinking of SQRoot(-1), not -x.
