well that's the thing, you should memorize as little as possible. it's not practical or necessary to memorize every single little formula there is

also pretty much any formula can be derived from a handful of basic identities/concepts

using ln x as an example, it's the inverse of ex, so putting them together as a compound function results in an identity function, as in ln ex=x and eln x=x

same way addition and subtraction or multiplication and division are inverses of each other

take ea=b, then ln ea=a, but since ea=b, you get ln b=a, since you're just plugging in b for ea

then you can generalize to integer bases. log10 is usually written as log

103=10x10x10=1000

so then log 1000 = 3, since log 103=3

The number e is an important mathematical constant that is the base of the natural logarithm.

also i drew all over the exam paper for molecular bio 101 and only properly answered one question worth like 10% of the overall mark and ended up scoring 56% (the pass threshold was 55%) which i firmly believe was because the examiners were just over it by the time they got to my paper and either wanted to reward me for giving them some levity or wanted to make sure they never had to mark one of my papers again

the question was about ethics in genetic transplant or whatever it's called and though i knew nothing about anything i absolutely knew that salmon genes are implanted into tomatoes to give them natural antifreeze properties and somehow managed to extrapolate that to a 500-word rant about the ethical dilemma of creating tomatoes that long for the open sea

Natural log and e trip people up all the time until they realize that it's just a constant. And the point of using that constant is to translate our arbitrary base 10 number system into a base *whatever* system which more cleanly reflects the natural world.

Unfortunately, the rote memorization of the prior-to-calculus is sorta necessary. You may not remember all the rules (nor should you need to, as stated in the quote above), but it's important in development of the requisite neurological pathways that allow one to manipulate the relationship between the links in a chain of definitions that comprise a logical progression.

Log is also more or less useless these days (I think,maybe). As I ostensibly believe it's original intent was to be able to graph on a piece of paper the relationship between exponential variables and still have it be nominally readable on said paper without having the lines fly off into outer space.

log i know has some relevance in programming due to the whole Big O thing

its relevance might be limited to being basically a synonym for "the runtime grows very loving slowly" as opposed to exponential growth which is defined as "what gently caress poo poo uhhh gently caress"

Exponential just means not linearly. Something that grows mondo slow can still be growing exponentially if it's to a factor of X^.1

True. Which would make it essential for Laplace transforms , thereby making it essential for computers to be able to do any calculus and usher in the modern age of computing. I stand corrected.

for example, a superbug has evolved that is resistant to the last-ditch antibiotic currently at our disposal so when that gets into an environment previously reliant on that antibiotic its spread will be exponential. meanwhile the number of times migf shits his pants in a given timespan correlates directly to the amount of attention people pay to him so the amount of poo poo currently in his pants grows linearly as more and more people turn to stare at the fetid brown snowball promenading through the streets of... wherever he claims to live today. it's basic maths

well i mean there's a difference in growth rate between x^c and c^x and afaik exponential is more referred to as the latter in big O while the former is just some other type of growth

im only relating how i think i learned it a year ago or so when i was taking online courses on programming algorithms so someone may be technically incorrect or just very incorrect (me. its me.)

This means Laplace was descretized into its constituent parts via dropping a dimension or two, that when cobbled together they approximate it's ersatz form, yet still remaining an abstraction as you can never really have a non 3d being in a 3d world.

Assuming Laplace was a pumpkin to start with, this statement is true.
