Why is a [math]\mathbb{R}P^2[/math] a real projective space if we can't embed it in [math]R^3[/math]? I'd call it fake instead.

Ps. nice duck.

It's analysis of the real numbers. Yes, there is also an "imaginary analysis". No fake one afaik, tho.

>>8462544
>fake
that's nonstandard

>>8462532
no, but there's "complex analysis"

>>8462532

"""""""""""""'Real""""""""""""""" analysis actually doesn't exist since the reals don't exist.

>>8462585
stick to your containment thread >>8461981

>>8462532
>Is there a "fake analysis"?
its called calculus

>>8462563
>complex analysis

Wow, what a pretentious name for a field of mathematics. Do mathematicians really feel the need to prove how smart they are so much that they name their field "complex"?

>>8463224
Mathematicians aren't all pretentious. you're a fucking idiot if you're serious. Complex analysis is the analysis of the complex field and is centre around i^2 = -1. you should graduate first before calling people pretentious. Fuckhead this is the Maths board

underrated

>is centre around i^2 = -1

What the fuck lol, I remember that bullshit from when I was in high school. What a load of bullshit. Like how can a number be the square root of a negative number? Lol like what the fuck? Can't believe mathematicians are wasting their time studying numbers that don't even exist.

>>8463237
You were probably told you can't "square root a negative number" when you were a little kid. We can if we define another field of mathematics. it's not bullshit, idiot.

Being baited that hard

>>8462532
Why do they call it "Lie theory"?

Is there a "Truth theory"?

>>8463263
There is a truth theory.

It is called rational trigonometry

>>8462563
Is there simple analysis?

>>8463285
I have a book called "Basic Complex Analysis"

>>8463263
Why do they call it game theory if we dont learn how to make an rpg?

Why do they call it game theory if we don't learn how to hunt deer?

>>8464078
Why do they call it measure theory if youre not even using a ruler?

>>8463237
Okay then, what's the solution to [math]x^2+1=0[/math]?
And why does it always pop up in physics?

>>8464123
It doesn't have a solution because you can't have a square root of a negative number, dumbass.

>>8463229
>Mathematicians aren't all pretentious.
Correct. They're all insufferable autists

>>8462532
Yes, it's called, "Engineering."

>>8463285
Calculus

>>8464848
Why not?

>>8464921
Please give me the numerical value of the square root of a negative number.

Pro tip: you can't.

I... I can't tell if you're the one who's been baited hard, or if you're intentionally acting retarded as bait.

Enough internet for today

>>8464945
I don't believe in complex numbers. I just believe in pairs of numbers from the reals with nifty $ and @ operations defined as
(a,b) $ (c, d) = (a+b, c+d)
(a,b) @ (c, d) = (ac-bd, ad+bc)
Messing around with pairs of numbers like this is super useful and interesting! You should try it! Fuck those stupid imaginary numbers though.

>>8464957
*(a, b) $ (c, d) =(a+c, b+d)
I am retarded and will commit sudoku immediately
