@Agawa001 yep

thanks

@MaryStar I was asking balarka sen.

What book are you studying?

@Rememberme Yep , I am reading that.

@MickLH Cool!

@Agawa001 Sorry , gotta sleep now. I'll post tommorow.

@Agawa001 nope

@MickLH Can it be done by series?

@Agawa001 Besides what about the $x$ numerator? it isn't $x+1$

@MickLH What method did you use?

@Agawa001 but then the formula doesn't seem to work? $a=1$ right?

that's right

yeah dumb me

wait i can complete the square

@MickLH It was on my test today.

Nice but there the denominator has a quadratic without a constant term. If I delete the constant from my problem , WA says the integral does not converge.

oh yes

Can someone help me finding integral of lnx/(x^2+2x+2) from 0 to infinity?

@Chris'ssistheartist You're right , sorry." It is sometimes argued that, in relative clauses, that should be used for non-human references, while who should be used for human references: a house that overlooks the park but the woman who lives next door. In practice, while it is true to say that who is restricted to human references, the function of that is flexible. It has been used for human and non-human references since at least the 11th century"

@Chris'ssistheartist *who not that . In your profile also ,it should be "A Romanian *who is climbing the peak of Ramanujan ..."

sub n=n-1

@Rememberme sum to n is n(n+1)/2

@Paradox101 (n)(n-1)/2

i use codecogs as well

don't worry about downvotes , that won't happen

answer it

also i just realized your name has a one at the end , i don't see htat either

my computer isn't showing the u

i hope not

oh god not again @Nosferatu sorry i thought your username was just nosferat not nosferatu (i only see nosfarat here , maybe it's getting contracted) .

I just found an actual blog about vampirism. How can someone actually belive in vampires.

archaic Romanian word

nosferatu means vampire

lol

@robjohn Till today I always read your name as robojohn.

Oh my god

can anyone help me with math.stackexchange.com/questions/1449991/…?

@Alessandro yeah I know about that one

is there any way to see most starred things posted in this chatroom?

you mean like rotating coordinate system?

@KhallilBenyattou Sorry , but i don't know what basis or e means

is there any way to find it by slicing parallel to arbitrary line?

We normally find area of a curve by slicing parallel to y or x axis

Hello

@MikeMiller Thanks for the term! WIkipedia has some properties.

@MikeMiller Are there some special properties of functions which are there own inverse? I'm asking because in geometrical optics , because of the principle of reversibility of light , you can interchange object and image.

@Hippalectryon All x,y

If f(x)=y and f(y)=x , what does that tell us about f?

So how can I simplify it?
