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

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

She is derivation, a transform of functions that describes rate of 𝑓(𝑥) changing as 𝑥 changes. (This can be represented visually as the slope of the graph 𝑦 = 𝑓 (𝑥).) He is the exponential function 𝑒^𝑥^, 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 −2 𝑒^𝑥^, which are... just... uh... derivative works

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

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

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^

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.

Oh, I was thinking of it as 𝑦 = 𝑒^𝑥^ or 𝑥 = ln 𝑦, whose derivative in respect to 𝑦 is 𝑥 = 1/𝑦 (for 𝑦 > 0) or 𝑦 = 1/𝑥 (for 𝑥 > 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/d𝑡 for less ambiguity, as @anothercatgirl suggested.

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

Here, have this:
𝑒ˣ
ᵈ⁄d𝑥

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

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.

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

You reached the end
