A cycloid is the curve generated by tracing a point on a smaller circle rolling around an bigger circle.
The word cycloid comes from the greek word “κύκλος” meaning “circle”. There are epicycloids and hypocycloids (smaller circle located above and beneath the bigger circle).
The cycloid is determined by the ratio between the two circle’s radii k=\frac{R}{r}.
More information can be found on this Wikipedia entry.

BASIC, mathematics, programming,

Using the same method used in my previous Sierpiński Triangle program, which is written in Python, I wrote a fractal generator for my graphing calculator TI-84 Plus in BASIC.

BASIC, mathematics, programming, #old hardware, #prime, #prime generation, #Texas Instruments, #TI

Being a fan of old hardware, I used the TI-99/4A (released in 1981) to calculate some primes.
The code is written in BASIC, the programming language found on most computers of this era.
Further information on the TI can be found in this Wikipedia article.

Using the programming features given on Texas Instruments’ graphing calculator TI-84 Plus, I created this text-base connect four game.
The code is written in BASIC and can be seen below.
To transfer code to and from the graphing calculator, I used Texas Instruments’ TI Connect™ CE Software [1].

Controls

  • Numbers 1 to 7 put your piece accordingly,
  • ‘clear’ pauses the game (for taking screenshots).
