I am a HUGE HUGE fan of all things math-related! I am trying to learn as much as I can about Python. Have a good day~!
Tic Tac Toe
Yes, I have been gone for a while, and I apologize for that. My huge PocketMonsters project has been put on hold for the sake of my sanity, and I want...
The Chudnovsky Algorithm
(NOTE: It only does 18 iterations, as if you try to do any more, it raises an OverflowError, how lame.. -__-) わーい, another π approximation method! (I...
The Riemann Sum!
Let's talk about the Riemann Sum!! Okay, so the Riemann Sum does the same thing that an integral does, as it is essentially measuring the area under...
EVEN MORE APPROXIMATIONS OF π!!
I'm back at it again, this time with a compilation of different formulae for approximating π, with surprising accuracy in some cases! Fascinating stu...
FIRST C++ PROJECT!!
Yay! With the help of my friend @AmazingMech2418, I have learned the basics of C++! Obviously the first thing I made was a π approximation program! I...
𝛑 approximations 3!!!!!
Yayyyy, it is time again, for a compilation of a few 𝛑 approximations!!! (￣ω￣)/ A few notes and things to consider: - Number 2 could have been more...
π APPROXIMATIONS 4!!!!!!!
Hooray, it is finally here! I struggled a bit with finding ones that I haven't done for this one, and I hope I've got original ones here for you all....
Today I'd like to teach you all about one of my all time favorite constants: π! Most likely, all of you know that π is the ratio of a circle's circumf...
Logarithms and Inverse Logarithms!
Okay, time for something fun that , for once, ISN'T related to π! (Lol) This program takes a user-inputted base and offset, and graphs the correspond...
Initial Sprite work for ポケットモンスター ^~^
Hello all ! I am so sorry for being gone all weekend, I was super busy . . T~T However, I do not think you will be disappointed, for I was working on...
Pythagorean Triples
I am so tired... T~T I finally finished it, after slacking off for a few days (やった!) This was honestly a bit frustrating to make.. (Lol) This calcu...
The Mandelbrot Set as seen on the Complex Plane
I nearly forgot to post before bed T_T I made this for a school project, but now that it is graded and fully optimized, I want to post it here ^..^...
Pixel Art Builder!!
Here is my submission! This takes a url to an image, and makes the turtle draw it! To use it, use [this program](https://repl.it/@LizFoster/TEMP). Co...
My work for Pi Day ^ ^
I wrote this up really quickly. It approximates pi, by using the Leibniz Formula/Series (https://en.wikipedia.org/wiki/Leibniz_formula_for_%CF%80)! A...
The Collatz Conjecture
Times Table Cardioid
Another challenge I did. This was quite enjoyable. Any thoughts on my code? (⌒_⌒;)
Recamán's Sequence
This is something I have wanted to do ever since I started learning about Python Turtle, as it is just so darn pretty! Recamán's Sequence is a set of...
Euler's Number Approximation
Hey again ^ ^" One of my shortest ones yet, this just solves for Euler's number, similar in structure to my Pi approximation code. Please enjoy!
Bubble Sort
From an English coder on YouTube called "The Coding Train". It sorts a set of random points using the bubble sorting algorithm. Does anyone have any f...
finding φ
The golden ratio (φ) is the number you get by doing this equation (when given a and b): a / b = a+b / a φ is approximately 1.61803398874989484820 (I...
Wallis Product (π again)
And another one!! That was quick (Lol) Using the Product operator (𝚷), you can skip all of the confusing ∫ math in the Wallis Product for π. This i...
Basel Problem
Alright, another way to compute π, done! This uses an infinite series (via the summation operator) discovered by our good friend Leonhard Euler, whic...
Circle and Sphere Statistics
Simple program that takes a user's input of a circle/sphere's radius, and outputs the diameter, circumference, and area for a circle, and the surface...
Search through π for desired values!!!!
**YES!** Not quite in time for pi day in America, but I already did something for pi day, so it's not all bad. Either way, I somehow did this in unde...
Prime Number Checker
This is fairly straightforward. It checks if the number you input is a prime or not. If it is not, it will tell you what its factors are. It should b...
Base 16 To Base 10
Nothing too special this time ^ ^* A short little program that converts Hexadecimal strings into Decimal numbers. Try setting "C9" as the input, and...
Binary Number to Decimal Number
Hello again all (⁄ ⁄•⁄ω⁄•⁄ ⁄) This is some simple code I wrote several hours ago and forgot to post. It takes a binary value inputted by the user, an...
Factorial Calculator
The "Product" Operator (∏) is the multiplicative equivalent of the Summation Operator (Σ). Among many other things, this can be used to calculate fact...
