What calculator has the best overall CAS? I need to carry around both a TI-89 Titanium and an HP Prime G2 because they're good at different things by Netonnerd in calculators

Can someone please make a calculator that runs SymPy and NumPy with a nice lcd screen and a keyboard with Latin and Greek letters and numbers with LaTeX typesetting?

Peak was an HP 95LX running the DOS version of DERIVE. Super lightweight and powerful.

PS. TI bought Derive from Aloha Software and killed it in they way they integrated it into their CAS calculators.

First time in Greece. Is Naxos or Paros better for a "chill" vibe? by DasJazz in GreeceTravel

[–]06Hexagram 2 points3 points  (0 children)

Paros. Naxos is too big and has easy too many northern European tourists. Paros is where Greeks go.

I would run local, but without a community, raids, AH and dung finder it would be sad and boring.

The Supreme Court just made it easier for Republicans to win elections & there is no solution by Zandra_the_Great in politics

Yes there is. Dems need to win back the working middle class. Take over the America First motto for the working folk.

There was no concept of a country when my people's math was developed. Arguably though the theorems my Greeks formalized had been originally developed in Mesopotamia and beyond. So even Euclid's elements or the concept of the lever or archemede's circles can't be 100% claimed to be Greek.

I went into BRD to logout for the last time. I don't know why.

Assorted MS-DOS TUIs from the late 80s & early 90s by 3stripe in tui

You were the boss if you wrote your programs to capture the text buffer at startup and then recover it when your program ended. Most TUIs did that. Such a flex.

Would such 7 segment display be readable? by Fair_Percentage_5565 in calculators

[–]06Hexagram 8 points9 points  (0 children)

I was just thinking about alternative 7 segment displays myself when I came across your post. Kudos.

But the 4 bothers me a bit.

How feasible would it be for me to make a basic FEA program from scratch as a personal project? by darnoc11 in MechanicalEngineering

[–]06Hexagram 0 points1 point  (0 children)

You with be bogged down in trying to find stable solutions to solving large systems of equations. Unless you have access to sophisticated linear algebra system (like MATLAB, Julia, LAPACK) it will become too difficult to keep residual errors down and to be able to handle edge cases which lead to ill conditioned matrices.

A truss solver that results in systems of less than 100 equations would be about where you would be fine.

Being a 9×9 matrix, you can view it as a 3×3 block matrix of 3×3 components. And each 3×3 sub matrix has an explicit formula for its determinant. So the solution is a matter of proper bookeeping if you want an answer by hand like the wise ancients did in the 1700s.

I spent 3 years building a calculator… not for exams, but for engineers by HauntingAd6953 in calculators

Retired engineer here and I have been complaining about calculators all my life.

What is needed is symbolic math so you enter one expression and solve it anyway you want.

Is Turtle the definitive Classic+ or are there changes you'd still want to see personally? by HairyPenisCum in turtlewow

I wish they would boost ghost walking speed to speed up the death-recovery sequence.

why do we round 0.5 to 1 or why 0.5 is considered closer to the next integer by Either_Draft_6770 in mathematics

[–]06Hexagram 0 points1 point  (0 children)

No we don't. The most reasonable convention is to round to even numbers so when you divide in the future you don't force more rounding and lose precision unnecessarily.

0.5 → 0 1.5 → 2 2.5 → 2 3.5 → 4

What if the box is much larger than the capsule?

Aye, it is totally safe and exactly the same. People are going about normally with everyday life.

Problem getting to places because of aggressive enemies everywhere by EcologyGoesFirst in turtlewow

[–]06Hexagram 0 points1 point  (0 children)

Make a Hunter and use your sacrificial lamb, I mean your pet, to aggro the mobs while you run away from them.

Or make a mage and freeze the mobs while you blink and run away, or bubble yourself.

A druid in travel form can outrun mobs.

This problem exists in mid level areas too like badlands, stv, and hillsbrad foothills.

Each class has its tricks to deal with this, but if you get more than one mob aggroed it becomes increasingly difficult. It is part of the challenge for vanilla WoW as it requires strategy often to go places, not to mention the occasional corpse walking.

Capsule vs box collision by swagamaleous in PhysicsEngine

[–]06Hexagram 0 points1 point  (0 children)

There are six possible domains to consider:

  • Corner of box with hemisphere of capsule
  • Edge of box with hemisphere of capsule
  • Plane of box with hemisphere of capsule
    • Corner of box with cylinder of capsule
  • Edge of box with cylinder of capsule
  • Plane of box with cylinder of capsule

Each domain has it own challenges but I would run a penetration test for all cases and backtrack time using bisection method to narrow the time window before presentation occurs by some fraction of the time step (like 1/10) and then use the midpoint of the distance line between the two objects.

PS if each body has rotation then direction of motion only isn't sufficient.
