She's going to find out he is stuck on on his E^x

Reminds me of a fun joke!

A constant and e^x were walking down the street. They see a differentiator coming, and instantly the constant gets scared shitless. The differentiator comes up, and as expected, POOF, the constant is gone. e^x starts laughing and says "nice try, can't touch me". But the differentiator tips his hat and responds "is that right?", then throws off his coat and shows that he is d/dy.

The result is π‘¦β€Š=β€Šβ…Ÿβ‚“, right?

[-] Papergeist@lemmy.world 24 points 1 month ago

No e^x doesn't have a 'y' and so it also acts as a constant.

Oh, I was thinking of it as 𝑦 = 𝑒^π‘₯^ or π‘₯ = ln 𝑦, whose derivative in respect to 𝑦 is π‘₯ = 1/𝑦 (for 𝑦 > 0) or 𝑦 = 1/π‘₯ (for π‘₯ > 0). Your interpretation is that the 𝑦-axis is non-existent or named differently, which is why I'd prefer the joke to say d/d𝑑 for less ambiguity, as @anothercatgirl suggested.

yayaya, or in other cases like multiple independent variables, I'm not sure because it's been 6 years since I took calculus

[-] MOCVD@mander.xyz 2 points 1 month ago

The general form would be implicit differentiation! d/dx dx/dy e^x = e^x dx/dy

[-] ChaoticNeutralCzech@lemmy.ml 3 points 1 month ago* (last edited 1 month ago)

Nobody exp(x) the y-derivation!

[-] prole@lemmy.blahaj.zone 20 points 1 month ago

It's nice to see memes like this and be surprised that I don't actually forget all of the calculus I ever learned

[-] 1984@lemmy.today 2 points 1 month ago

For me all that calculus I did has not been used in life ever afterwards. :)

[-] Illecors@lemmy.cafe 20 points 1 month ago

Any explanation for the mathematically challenged?

[-] ChaoticNeutralCzech@feddit.org 45 points 1 month ago* (last edited 1 month ago)

She is derivation, a transform of functions that describes rate of 𝑓(π‘₯) changing as π‘₯ changes. (This can be represented visually as the slope of the graph 𝑦 =β€‰π‘“β€Š(π‘₯).) He is the exponential function 𝑒^π‘₯^, which is the only* non-zero function whose derivative is itself - in other words, unaffected by derivation. The number 𝑒 is a constant (around 2.718) and the base of natural logarithms, hence the title.

* except its multiples such as βˆ’2β€Šπ‘’^π‘₯^, which are... just... uh... derivative works

[-] Illecors@lemmy.cafe 6 points 1 month ago

Much appreciated!

I think you forgot about e^x + 1, and e^x + 2, and … …

(My profs always dunked on me for forgetting the + c and I can’t resist doing it to someone else, I’m sorry)

For real tho, great explanation

[-] knomie@feddit.org 6 points 1 month ago

But the derivative of e^x+c is just e^x (which for c!=0 is not the same). That's why the +c is added during integrating because all +c is derived to 0 and thus indistinguishable.

[-] felsiq@piefed.zip 2 points 1 month ago

I wish I could say I commented this late at night or something, but nope I’m just dumb lmao thanks

[-] arschflugkoerper@feddit.org 18 points 1 month ago

The derivative of e^x is e^x

[-] teft@piefed.social 12 points 1 month ago* (last edited 1 month ago)

If you want to use exponents on the fediverse you have to enclose the entire exponent in carats like so without the spaces:

e ^ x ^

e^x^

[-] anothercatgirl@lemmy.blahaj.zone 2 points 1 month ago

how about derivative with respect to time instead of with respect to x?

[-] ChaoticNeutralCzech@feddit.org 10 points 1 month ago

β€Šπ‘’^π‘₯^ has been around since the 17^th^ century and it hasn't changed since. Therefore, it's a constant with respect to time and gets unceremoniously derived to 0.

[-] NobodyElse@sh.itjust.works 3 points 1 month ago

Well played!

[-] anothercatgirl@lemmy.blahaj.zone 3 points 1 month ago

very nicely said, I agree

[-] abbadon420@sh.itjust.works 12 points 1 month ago

Couldn't figure out how to do superscript. But you know I watch 3b1b. I'm not sure if this meme actually fits though.

[-] ChaoticNeutralCzech@feddit.org 16 points 1 month ago

Here, have this:
𝑒ˣ
α΅ˆβ„dπ‘₯
β„’

Even plain text textboxes can do fun stuff if there is good Unicode support

[-] sartalon@lemmy.world 4 points 1 month ago

My favorite thing about Laplace and Fourier transforms was making a fabulous looking F and L.

Their functions are so fucking spectacularly useful, but I just loved writing it out.

[-] ChaoticNeutralCzech@feddit.org 2 points 1 month ago* (last edited 1 month ago)

Mine too! I looked through all of Unicode and they don't have the awesome-looking L I know from college, only the "script" variant.

[-] teft@piefed.social 3 points 1 month ago* (last edited 1 month ago)

Carats on both sides of the exponent so ^ x ^ but without the spaces. e^x^
