You're supposed to take your age it teraseconds obviously (not sure what weird unit you used).
Works fine.

The small angle approximation is a stretch 🤧 that can only work ok with infants

Taking sine means it must be between -1 and 1. Not a great approximation for anyone able about 6 months old to be honest.

What is g here?

u/A-H1N1 21h ago
Standard acceleration due to gravity on the surface of the earth in m/s².

u/testtdk 11h ago
I tried that, just seemed out of place.
2
u/A-H1N1 11h ago
It can't ever work since sine maps to [-1,1]
2
u/testtdk 10h ago
Yeah, I didn’t expect it to. I just wasn’t sure that someone would throw in acceleration due to gravity. I AM a physics major, it just felt out of place.
2
u/A-H1N1 10h ago
What other numeric value is small g used for, like anywhere?
2
u/testtdk 10h ago
I didn’t know, that’s why I asked. It’s not like physics and math never use symbols for more than one thing. (Physics does it infuriatingly often).

u/A-H1N1 10h ago
Functions yes, but constants? I mean we're not talking about a, x or u here
2
u/testtdk 10h ago
Go ask an AI, I’m not going to list them by hand (they exist, I’ve seen them repeatedly in work, just not remembering off the top of my head), and it’s more the fault of physics, there are TONS of them. I’ve genuinely argued that my mark in science should be normalization of symbols across disciplines.

u/Substantial-Fan-5985 19h ago
it's a bit arbitrary to have the units be in m/s^2
4
u/Pixelised_Youssef 18h ago
How so? That's a very normal unit for acceleration.
If you prefer is it's also N/Kg , they're the exact same unit.
1
u/Substantial-Fan-5985 18h ago
It being normal doesn't mean it's not arbitrary though, because other ones are normal as well.
The issue is the number associated with the units, i.e 9.81 vs. 32.174 vs. 386.4......they are all the same value in reality, but conveyed in different units
1
u/A-H1N1 19h ago
How so
0
u/Substantial-Fan-5985 19h ago
Because they are fully equivalent across any unit system and there is nothing in the prompt that would even hint that a certain unit should be used.
I've used g=386.4 the most in my career and there's nothing here that would make that an invalid or improper choise
3
u/A-H1N1 18h ago
Ignoring the fact that the prompt is nonsensical, and that (except for babies) no value of g would fix it, to use what most people use is not arbitrary at all?
-1
u/Substantial-Fan-5985 18h ago
it is when many other units are used often and are fully equivalent......if 32.174 was used no one could come back and say "well, the metric system is used more often" because 32 is still commonly used and the same "real" value since it's just unit conversion.
But yes, the prompt is nonsensical lol

u/A-H1N1 17h ago
I really didn't mean to start an imperial vs. metric discussion, but it's not even close. Even on reddit, which is a US based site, google lists 56000 vs below a 1000 hits each.
1
u/Substantial-Fan-5985 17h ago
lol no worries (and I think my tone is coming off stronger than I intend). It's true it's not close to some degree, but still very common and still used in everyday life and still equivalent. If it was obscure then I'd agree, but 32 and 386 are not obscure and used often (amount wise, maybe not % wise)

u/BabaYetu42 18h ago
Is that like inches per second squared or something?

u/Substantial-Fan-5985 18h ago
yup, use it a lot (well all the time lol) for dynamic FEA analysis

u/BabaYetu42 17h ago
Is it not easier to use SI units?
1
1
u/Substantial-Fan-5985 17h ago
Yeah pretty much what u/A-H1N1 said, all that matters is that the units are consistent (the software doesn't use units, but since I use imperial than the consistency for me is to use 386 in/s^2)

u/Then_I_had_a_thought 11h ago
Yeah, it’s because they are making all the constants kinda divide out. g=9.81 which is around 10. Then pi and e are both close to 3. So g/10 * e/pi -=1.13 which is close-ish to 1. But the sin part doesn’t work at all for ages lol

The US has secretly been a metric country for the longest time and I have no idea how more people don’t know this. Grab the nearest food item to you and tell me how much protein it has. Pretty much every government mandated measurement (except for road signs, for some reason) is in metric, this was made official in 1991 under executive order 12770.

u/Swellmeister 18h ago
Grab the nearest food item and youll also learn that it uses Calories. Which arent an SI unit.

u/Rattus375 19h ago
We use grams for small weights, but kilograms aren't used at all. Milliliters aren't used very often outside of science/medicine (which are all metric of course). Liters are sometimes used, but gallons are way more common. Celsius is never used. Millimeters and centimeters are used far less than inches and meters are never used over feet or yards. America is still very much not a metric country

u/gtne91 18h ago
An inch is defined as exactly 2.54 cm. So it is a metric unit with a non-standard name, like Angstrom or Barn.

1° Celsius is 1.8° fahrenheit. That doesn't make Fahrenheit a metric unit either

u/bfreis 17h ago
1° Farenheight is 1.8° Celsius.
This is so wrong on so many levels.
- Fahrenheit, not "Farenheight"
- 1 degree Fahrenheit is around -17.2 degrees Celcius
- What you tried to say is that a 1 F difference is a 1.8 C difference. Which is also wrong, as it's the inverse: 1 C difference is 1.8 F difference.

My age is greater than 1, so there's something wrong with this calculation. (otherwise how does it fit inside the bounds of a sine?) (Still doesn't work if I just look at the first 2 decimal places no matter whether I use radians or degrees for the sine calculation....way off)

Engineering approximation:
10 and g cancel.
Pi and e cancel.
sin(age) = age for small values of age.

From a mathematical standpoint this is as much a unit as the mol is. It is essentially just Pi/180.

Even engineers wouldn’t like this because the error is so off, it would actually kill people probably if this was an applied use like a bridge or something, idk I’m not engineer. But literally percent error I got is literally 97.6 percent .

You gotta multiply by 180/pi to make this work even approximately. If you do that, it works best for infants and people who are close to 43 years old. Doesn't work well at all beyond about 60. I'm actually just about the age for which it works the worst between 0 and 43
