I’ve taken like four or five advanced trigonometry courses and I still can’t really define what trigonometry is. Mathematics is like Andrew Tate’s Hustler University scam. If you take one class, it only exists to prove that you’re a mark and sell you more classes.
I have a masters in math and I have no fucking idea what a second course in “advanced trigonometry” looks like much less a fifth
I enjoyed the trigonometry unit in my highschool geometry class, but that’s because it was mostly proofs, and those were just philosophy about triangles.
Trig is basically the study of a wiggly line and how it turns out to be useful everywhere
Pythagoras: Everything that exists is a number. Except irrational numbers. Fuck those things.
If you change “number” to “vector” you’d have mathematicians agreeing with half of those.
But a vector is a number, no?
Not really.
It can be, but it doesn’t have to be. For example, real numbers can be viewed as a one-dimensional vector space over the field of real numbers. And what even number is? We don"t definine this term. We define real numbers, natural numbers, complex numbers but numbers it self have no well defined meaning.
A vector is a thing that can be added together and scaled in “the intuitive way.” That is, for example, if a and b are numbers and v is a vector, then av + bv = (a+b)v (vector addition distributes over scalar multiplication). The prototypical example is the collection of arrows rooted at the origin on the 2D plane, where addition has a simple geometric interpretation (you put the tail of one vector at the tip of another, the resulting point is the new tip) and scaling is “stretching.” But it really could be anything that adds and scales.
klein bottle is a number
It’s true, my great grandma just turned klein bottle years old
Do you have a version without the white lines?
Here you go
numbers aren’t real dipshits, they’re just letters that want to be special
boo
g-g-g-ghost!
Jinkies
data: NaN
data: 1
NaN is 0
NaN is specifically not a number.
> typeof NaN "number"Conclusion: Javascript is Neutral Evil
Always has been
Now that’s a characterization I can get behind!
That is a valid point. Also, I learned something about JavaScript. Thank you!
Well, it’s something like the difference between
{ x: null }and{ }.
Well, at least it is used in place of a number. But what about QED.?
That’s why it’s in the Evil row
I feel like it belongs more in the chaotic row
X can be a number.
X is a letter.
Let x be any number. => x is a number. QED.
X is ten, as the Romans do
X is a dying website
X marks the spot.
X is close button.
