Moments when you stopped watching a math youtuber.
>>
Did you watch his videos because you hoped to marry him?
>>
>>16826451
No, I wanted to learn something without faggotry being shoved in my face. You sound like you'd like it. Check it out!

buy an ad, chris

So does anyone know any better trick than to -r+r on the top to get sqrt(z^2 - r) + r/sqrt(z^2-r)

Then for the first term, z = sqrt(r) sec(u) so sqrt(z^2 - r) dz = sqrt(r) tan(u) * sqrt(r) sec(u) tan(u) du = r*[sec(u)*sec^2(u)-sec(u)]du

Then for the first term, you integration by parts so \int sec(u)*sec^2(u) du = tan(u) sec(u) - \int tan^2(u) sec du, so now we got the same term as above so you solve shit, then put it all together?

Wasn't he the ex-FBI guy? Or was it someone else?

I know you are, but what am I?

>I know you are, but what am I?
A faggot
>>
>>16826513
I think you should make z=\sqrt{r_s}cosh(u). Then dz=\sqrt{r_s}sinh(u).
The integral becomes 2\int cosh^2(u) du = \int [1+cosh(2u)]du=u+[sinh(2u)/2].
Then there is the whole schtick of getting back to z using expressions for inverse hyperbolic functions, but you get the idea
>>
>>16826448
3 variables:
L_0, z, r_s
L_0zr_s
L0zrs

>>16826934
Yes, yes, way better

Why is eigenchris popular?

He's making intro to special relativity videos for 10 years and responds on X to babby math like he never went to uni himself.

Maybe I'm bitter but this gives the ick, doesn't it.
>>
>>16827781
He's popular because he explains things pretty clearly and there's something vaguely soothing about his monotone and a lot of his stuff there just isn't anything else good at all. It's either way too low level or only for people who already know it.
But apparently he's a giant faggot.

stop being a snowflake
>>
>>16826452
Based, it's the same reason I hate babies/kids. We get it, you had sex, just stop shoving it in my face
>>
>>16827871
go back
>>
>>16827781
If you're familiar with the subject. No books actually cover the stuff in his videos. The closest is probably 1 page of John Baez' book.

Literal gap in the market.
>>
>>16826451
Not that guy but I also stop watching and even unfollow math youtubers when they posts that kind of bullshit because it is proof they are incompetent.
Why didn't he use the real name of eigenchris's boyfriend? Maybe he fears people would follow that fag instead of him because I do that whenever a failure thanks somebody else for something he couldn't solve or got wrong.

faggot anime website, the very fact you are here means your going to have your dick cut off within 6 years

are straights this sensitive lel
