WHERE DO I GET ONE?

WHERE?

>>7117081
just a normal chalk drawing compass, though i prefer it made of wood

Drop action pencil + ballpoint + marker + mechanic that works with graviation + eraser

the greatest chalk of all time

Do they still use compasses and protracters in math classes nowadays?

my geometry class in high school had those, but that was years ago so i really couldnt say

B A S E D
A
S

Damn straight.

Yeah we had grid paper too and of course rulers. I saw some plasticky looking geometry kits at a dollar store a while back and asked myself whether the old school tools were still being used with the advent of matlab and full computerization everywhere.

I really need to get a chalk board mounted in my room. I used to have one as a kid, and I think I could really use one now.

Not using a TI 36x solar (I'm talking about the first one, not the shit tier second edition).

>>7121102

lmao not even programmable

>>7121102
This and the 36x pro are the only calculators for me.

Why would you even want to program your calculator?
You don't need to use them for projectors anymore since every classroom has a computer projector and you can just put up grapher files.

>>7121138
>using a programmable calculator
Have fun being a cock munching engineer.

How good is the solar cell on the TI-36x Pro? I tried using a 36x Solar II for a while after my original 36x Solar I broke but the solar cell was absolutely terrible (either that or the calculator itself just drew more power). I could barely use indoors unless it was under really bright lighting and overall it just sucked. I bought another 36x Solar I off of amazon and have been skeptical of TI's "overhauls" ever since.

The wiki page's description of the TI-36x Pro also makes it sound fairly questionable.

The solar cell has always worked fine for me. I teach calc and recommend it to all my students, and I've only heard good things from them about it.

I've never experienced the mentioned programming bugs, although I never check my calculator's math that carefully.

>Why would you even want to program your calculator?

are you serious?

>>7121170
I own a computer with grapher and mathematica on it. Why would I ever want to fuck around with a brick from the 1990's? I get that you guys take your calculators seriously, but don't act like that's a universal thing.

>>7119375
In my trig class we use em. Not everything is computerized yet.

>>7119375
I'm using a compass in my transmission line/antenna theory class for smith chart plotting.

It's more convenient to do basic math work on paper than electronically, and it may forever be the case.

literal garbage

Not using a TI-89? GTFO.

>tfw not allowed to use forward calculators in most classes because "muh memory"
Fucking bullshit.
