i recommend jade calculator for a mobile (android) calculator. its really pretty, and a lot more powerful than sideways iphone

I think it's actually Turing complete

Edit: It is

bruh

Well, I did it on something called "GeoGebra" and in CAS (a function within GeoGebra). It's basically a maths-program which lets you find values for limits, draw graphs, etc. You basically just use a computer program to do the calculations.

>Coding is a part of programming that deals with writing code that a machine can translate. Programming is the process of creating a program that follows certain standards and performs a certain task.

It's evident when you think about the fact that python code is used in programs.

Also, I haven't seen every comment in this thread, but no one in this case is writing latex code, python code, matlab code, etc...

May I introduce sagemath it's free (in which you don't have to pay money which is good) it's got all the algebra tools, and will try very hard to preserve actual value, and it can interface with the python Jupyter notebook

also libqalculate comes with a banger cli calculator that preserves actual value too

For android use https://vancedapp.com/, it blocks ads and the videos load more smoothly too. Also can play videos with your phone off without shilling for Youtube Premium

Use Ublock origin for Web

Both are open source

Them text faces tho. I wrote and Android app ASCIIMOS, a keyboard to type out text faces like ( ͡~ ͜ʖ ͡°) ¯_(ツ)/¯ (∩∩). Check it out on the Play Store . https://play.google.com/store/apps/details?id=com.ng.emojikeyboard

Play here. Make that red line intersect with the green one. If the red line is perpendicular on the green one, you basically have 2 right angles and the length of the green side becomes 0.

It’s like math you’ve gotta do exercises and get a small intuition. Looking at definitions isn’t very helpful. Here is a book I enjoyed, in case you’re interested:

"The sum of an unknown quantity and a number equals the sum of the squares of the unknown and the number, augmented by twice the product of the unknown and the number."

or, as Joseph Mazur would have you believe

(x+a)^2 = x^2 + a^2 +2xa

Baldor Algebra.

Is the most popular book in the Spanish language for learning algebra (it also has versions for mathematics and geometry).

I'm making my way (very slowly) through this book (https://www.amazon.com/dp/0486417409?psc=1&ref=ppx_yo2ov_dt_b_product_details) and the two of you have summed up pretty completely everything I think I actually understand.

Well to measure a diameter, you take two flats, but the directly across from each other, and measure that distance with a ruler. It's pretty easy to make a tool that does this every time. To measure a radius, you have to find the center of the part, and that's pretty hard.

The book "Gödel's Proof" does a good job explaining it without getting too much in the technicals. If you really wanna understand it, I'd recommend it. You could probably get through that book in a day if you really tried, and you'd definitely walk away understanding how it works (at least at a high-level).

So apparently things that are Turing complete aren't programming languages?

Well I’d first suggest going through the basics, theres a great course in brilliant that I could recommend with this link, after that you can check out the courses that precedes this course.

In general when you learn math you usually take the following path

Basics -> Algebra 1 -> Algebra 2 -> trig -> calculus -> college math (linear algebra, etc)

Yes so for that particular limit, that is the case, but because 0^0 is one of the seven indeterminate forms, there are situations where "equivalent" limits can be proven to be something else. As in, lim(x->0+) [x^x ] is not the general case for 0^0, just as lim(x->infinity) [x^0 ] is not the general case for infinity^0 , which because infinity is not a real number, is also indeterminate and thus, cannot always be taken for granted to be one. (Incidentally, the limit(x->0)(x^0 ) is zero, not one. Don't believe me? Graph it.) Limits like that often do end up being 1, but my point is that you can't take it for granted, and if you run into an indeterminate form, you have to find the limit using L'Hopital's rule every single time (unless you have like limit (x->infinity)((3x^15 + 9x)/ (5x^15 + 6x^3 ) ), it's clearly 3/5 because of the leading coefficients; if you did LH rule 15 times that's what you'd get).

I think this page might help put things into perspective. It's a big topic in Calc II because of how the functions that define infinite series and improper integrals are written, and the fact that both operations usually require limits approaching infinity.

I'm trying to do this problem for my coding lessons

Since you’re an engineer(?), I found this on Amazon as commonly bought with the Handbook of Math seen above. As a physicist I kinda want it.

Might I introduce you to the HP Prime Lite? I have yet to find the difference between it and the 20 buck variant pro version, so I wouldn't advise that but it's worked great for everything I needed so far. Granted I do own the real thing so I use that 9/10 times so I very well might just not have used whatever function is behind the paywall but this is definitely better than any sideways calculator I've seen.

Mathally graphing calculator + has been my GO-TO for many years, it is old, hasn't been updated since 2014, has some compatability issues with newer phones, but god damn it is it a good and easy to use calculator!
