The birds also wanted to learn calculus

[RedTitan]

Thank you for explaining why the integral of 1/x is equal to ln|x| + c

[NotJames]

That's amazing. I've never seen that before

[hashemwannous]

Oh, so it wasn't just a rule we should memorize after all? It had an explanation this whole time? Dang.

[wristdisabledwriter]

Dang I’d love to see a teachers reaction to that

[xinpingdonohoe]

This is similar logic to showing why the contour integral around the unit circle of the function 1/z is 2πi.
z=e^(it), dz=ie^(it) dt
0≤t≤2π for one rotation.
dz/z=i dt, so 2πi-0i=2πi

This means the birds are currently smarter than me

[souravmohanty]

Lnx +c thanks sir 🙏💯 ever best teacher

[AlexandreAbreu]

Thank you! Now I don't have to memorize the integral of 1/x is ln |x| + c, but I have to memorize that x = e^t. Why did you do that? What's the logic behind it? Thanks again

[Ben-rdmg]

This would technically be a proof wouldn’t it?

[CheesedogIsWhat]

I haven't learned this yet (I'm on 8th grade), why do you always put "+c" ?

[sepdronseptadron]

Does this work with every integral? Like u subbing the solution and it'll collapse down to just the integral of 1?
Ig possibly with a lot more rearranging

[fmzm]

Expontial function yes but not any function. Because ?

[SuperYoonHo]

ln|x|!!! My chicken would like to learn calc sir

[dr.rahulgupta]

Sir You have represented the same which I suggested earlier . This is not fair .
