i remember the exact moment in high school when i understood what a derivative was. my teacher projected a plot of cos(x) over a plot of sin(x) and i saw the relationship between the slope of one and the position of the other. pretty rad breakthrough moment, imho.

anyways, i am very glad that nowadays i have computers to do my math for me.

I think it's pretty cool how arctan is a transcendental function but the derivative is a rational function

idk what this means but in my game I had to use a acos2 function to get an angle from somethin or something [it made sense at thrtime] and it was like, what magic is this

well it's like, you think of functions like arctan and log as smoky bullshit that you can't calculate without a table or calculator handy

but then you try to figure out rate of change and it's simple stuff. ln(4)? who the gently caress knows. 1/4? son do you take me for a kindergartener

Aren't there arbitrary precision summation algorithms that were used back in the 17th century too? They don't teach that stuff anymore.

Sorry, No. Not everyone was a special AP class snowflake. I was bored out of my loving mind in the babby tier maths because of political bullshit out of my control.

There were days where I could DO the homework proofs on the board in less time than it took other students to copy it out of their notes.

I hate your breed of pompous pretentious, "didn't do it in high school" hater. Go gently caress yourself with a cactus.

I found solace at the time in cheap Catholic school gurl pussy and Dungeons and Dragons.

I wouldn't trade my experiences, otherwise I might be like bump.

edit: No, they kicked me out of the AP English track because I "didn't take it seriously enough" I earned a 96% grade, though.

if i were a movie director i would hire a sperg to be my continuity person; that just makes sense

of course i would probably also gently caress with him by including a train in my film which would randomly change from one locomotive to another in different scenes
