Actually it makes sense to calculate "analytically" (symbolically) as long as possible and only after that doesn't help anymore, go to "numerical" calculations.

Man, calculators with fraction support weren’t all that common when I was in school.
Now imagine having a calculator with symbolic math support and the ability to solve derivatives and integrals with unknown variables. And I took that shit into the SAT because the TI nspire CX CAS was allowed. (Apparently that changed just this year holy moly)
This post is how I learned they exist.
look for ≈ on your calculator, try 22/7, the answer may surprise you
Probably my favorite approximation of pi. With four symbols, you have like 18 digits.
Do you, though? Pi starts 3.141592, but 7/22 starts 3.142857, already wrong by the 4th digit.
Shit! You're right! Guys... I uhh, I gotta go stop a satellite launch.
355/113 is my favorite
Using 7 chars to represent 8. Now that's efficiency!
The efficiency is that it is easy to remember 11 33 55
If you want efficiency, just remember the number and cut the operation.
Nowhere did he state that the 18 digits would be correct
like 18 digits
The simile stands.
You have to press =
Decided to try this by hand just for the fun of it. I stopped at twelve decimal points because it seems to just go on in a loop forever and I can't do this all day. 2.571428571428....
Yeah, n/7 does that. It's a loop of 142857, and changing the numerator shifts where in the loop it starts.
They also go in a pattern where the 'loop' starts with the Nth largest number in the sequence. So:
1/7= .142857 repeat 2/7= .285714.... 3/7= .428571... 4/7= .571428... 5/7= .714285... 6/7=.857142...
Im going to have to save this post and study it again when ive got more attention span. I fucking love it when numbers get weird. Thanks a lot!
If you want a rounded answer, press the rounded answer symbol. If you press the exact answer symbol, the calculator will give you an exact answer. It can't guess what you want, you have to tell it.
2 4/7
Check your settings
Reboot the calculator too
but there's a more important math question,
with heavy and deep philosophical implications...
What's
9 + 10
syntax error?
look at this smartass:)
it's an old one
i missed it too initially
but you bette remember the answer, it will be on the exam :)
i don't get it
2.57
Amazing. Some kind of AI
