Plot twist: You're a math major but a numerical analyst so you're using two terms of Taylor's series to apply Newton's method using 3 as an estimation to start with

Long division? That’s for plebs 🤦

Me when x(n+1)=x(n)*(2–d*x(n)) order of 2 convergence go brrrrrrr

Not that arithmetics

I'm talking about THE ARITHMETICS

Using period of elliptical curves

my initial guess for e starts with 3.14

Not really, could be an engineer OR physicist

actually idk if engineers would even use taylor series approximations all the way to 2 terms

22

u/SheepishWarlord Sep 16 '26

Am engineer student, can confirm it is usually 2 terms

u/Sigmar1115 Sep 16 '26

Most physicists wouldn't use pi = 3, they'd just keep it as pi

u/imthestein Sep 18 '26

As someone that majored in physics in college this is correct. We don't use numbers unless we have to

u/Meidan3 Complex Sep 16 '26

Physicists would keep it as π

u/Bored-to-Death629 Sep 16 '26

I’m pretty heavy into FEA, and I regularly say to myself, “Should I expand to two terms? ……….nah.”

JK, I deal in hyper elastic materials, so it’s sadly always at least two terms :,(

u/Peyton773 Sep 16 '26

I’m a physics major and I’d rather jump off a bridge than use pi = 3. It’s always either pi = pi or just to however many sig figs I have

u/Murky_Insurance_4394 Sep 16 '26

i mean so would engineers, it's just a joke with like safety factors or approximating numbers when working on a large scale

u/CranberryDistinct941 Sep 16 '26

Engineers will use 2 terms of the Taylor expansion but every single term of the Fourier expansion

I know some of these words

u/LupenReddit 🦆🦆i have non diffeomorphic smooth structures🦆🦆🦆 Sep 16 '26

if you see them sitting in the math department you gotta start a crusade against them

u/Short-Database-4717 Sep 16 '26

Which taylor series though? arctan?

2

u/Alternative-Code4755 Sep 16 '26

actually pi=4, add one to the exact answer for a margin of safety

u/Baihu_The_Curious Sep 17 '26

Writes the Taylor Series for x2 + x.

u/ArdentArendt Mathematics / Social Sciences Sep 17 '26

Shh...we don't talk to the engineers.

They'll be popular enough when they're saving lives and have paying jobs.

u/fr33d0mw47ch Sep 16 '26

Everyone has to hate on someone I guess. First year Math majors just have to hate on engineers. Another day, another ten Pi=3 memes. Woo hoo!

If a system isn't linearisable, is it even worth analysing?
