As a side note, I'm taking a refresher math course and ChatGPT is fucking awful at math. Which is pretty weird because I was told it was the best use case scenario for it?

Definitely see why programners aren't really worried about it taking their jerbs

Interesting, what kind of math? I find chatGPT is excellent at analysis and probability theory, less so in algebra, but still serviceable.

[–] DragonTypeWyvern@midwest.social 2 points 15 hours ago

Calculus, so, yeah, more or less algebra with depression.

A quarter of width times height divided by the inverse of pi

engineers use d²π/4 as you can't measure the radius of a pipe or a similar 3d solid object only diameter.

[–] stebo02@lemmy.dbzer0.com 17 points 1 day ago (1 children)

or engineers are not smart enough to calculate r=d/2 first

[–] idegenszavak@sh.itjust.works 9 points 1 day ago (1 children)

Why would i calculate r? I need only the area. See? Why would I waste my time for an extra calculation.

[–] stebo02@lemmy.dbzer0.com 7 points 1 day ago* (last edited 1 day ago) (1 children)

Just do it in your head? The diameter is 5.62, so the area is π*2.81², which is more efficient to type in your calculator than π*5.62²/4. You're the one wasting time.

Life is too short to waste for such things.

[–] GluWu@lemm.ee 2 points 1 day ago (1 children)

I use the measure tool in solidworks

[–] idegenszavak@sh.itjust.works 2 points 1 day ago* (last edited 1 day ago)

You just imported a point cloud, so you can't snap to the centerline, you can only measure the diameter.

[–] pixelscript@lemm.ee 2 points 1 day ago

This actually explains some of the formulas in research papers I've read.

No its actually r^2π

[–] queermunist@lemmy.ml 7 points 1 day ago* (last edited 1 day ago)

Just make equations into songs. I still remember the quadratic formula and I haven't done any algebra in ten years.

I surprised myself at remembering this one. Possibly the mnemonic of a tasty square pie helped me remember all these years.
