artgallery.zip11k17-04-03File is not ratedArt Gallery
The user enters n vertices of a polygon without self-intersection. It is the floor plan of an art gallery. The user's task is then to pick at most [n/3] (the square brackets simbolise the floor function) vertices where to place guards so that they cover the whole interior of the gallery. It is understood that the guards may look in any direction they choose and that their view is blocked only by the walls.
baseconverternspire.zip14k12-04-05File is not ratedBase Converter Nspire
This program will convert your numbers in between different bases up to base 36! Made with Nspire Lua, for OS >3.0
bayes.zip19k15-01-28File is not ratedBayes' Theorem
This program offers a guessing game the user can play against the calculator. The user fills three baskets with up to ten balls in four different colors. The calculator then chooses a basket at random. The user's task is to guess which. As evidence the calculator draws balls (with replacement) from the chosen basket and discloses their color and number. With the help of Bayes' formula, a new probability is ascribed to each basket. The user can now guess the number of the chosen basket or order another draw until the probabilties become more clear.

conics.zip17k15-01-19File is not ratedConic Sections
The program constructs a conic section through five given points. The user can move the point marked by a circle with the arrow keys and watch how the conic section changes. The coefficients of the corresponding equation can be displayed.
crosscut.zip8k15-02-12File is not ratedCut the Cross
It's a popular game to divide a square with a few straight cuts and to form new shapes from the produced polygons. This program works the other way round. With the help of a moving square grid, the user effects at most four cuts on a swiss cross. His task is then to reassemble the pieces to a square.
cubicsplines.zip8k16-07-17File is not ratedCubic Splines
The user enters up to 52 points, "nodes", in the Euclidean plane. The program then connects these points by a function graph (x,y(x)) (press [Enter] or [blank]), where y(x) is a natural spline, or by a curve (x(t),y(t)), where x(t) and y(t) are natural splines (press [.]), or by a closed curve (x(t),y(t)) composed of periodic splines, press [,].
curlicues.zip5k16-02-24File is not ratedCurlicues
The user enters the functional term x(n) of a sequence of real numbers, for example x(n)=n^1.5. The program then constructs the following sequence of plane points: (u,v)(0)=(0,0), (u,v)(n)=(u,v)(n-1)+s*(cos(2*pi*x(n)),sin(2*pi*x(n))) and draws the line segment between consecutive points. A number of curious curves arises.
curveshortening.zip16k16-12-16File is not ratedCurve Shortening Flow
The user enters a closed curve c. The program then moves each point of c in the inwards normal direction with a speed proportional to the signed curvature at that point.
cutsquare.zip5k15-07-19File is not ratedCutsquare
The user's task is to cut the unit square into four polygons and then to form a triangle by rotating and translating the parts. A special choice of parameters yields an equilateral triangle.
ellipticbilliard.zip6k15-10-16File is not ratedElliptic Billiard
The user enters the initial position and direction of a ball on an elliptic billiard table. The program then traces the path of the ball starting in the given direction. You can also try to hit a second ball going via the border.

graecolatinsquares.zip6k15-11-16File is not ratedGraeco-Latin Squares
A latin square of order n is an nxn-matrix of n different symbols (e.g. numbers, letters or colors) in which each symbol occurs exactly once in each row and each column. Let S and T be two sets of n symbols each. A graeco-latin square of order n over S and T then is a matrix M of ordered pairs (s,t) in SxT, in which each pair occurs exactly once and which decomposes into two latin squares if s and t are considered separately. For n=2 and n=6, no graeco-latin squares exist. The program displays graeco-latin squares up to order 10.
hamiltonianpaths.zip10k14-12-27File is not ratedHamiltonian Paths
A Hamiltionian path on a graph is a path that visits each vertex exactly once. A Hamiltonian cycle is a closed Hamiltonian path. The program allows the user to define a graph on the screen. He can then proceed to construct a Hamiltonian path or cycle on this graph if possible. He can get hints from the program.
hilbertcurve.zip5k16-06-30File is not ratedHilbert Curve
The Hilbert curve is a continuous mapping c:[0,1]->[0,1]x[0,1] from the unit interval into the unit square whose image is the whole square. It is the limit for n->infinity of curves cn which consist of horzontal and vertical line segments. The program draws these curves up to n=7 (n=8 for a computer screen).
hyperbolictiles.zip6k15-04-21File is not ratedHyperbolic Tiles
The program demonstrates the fact that the hyperbolic plane can be tiled by regular polygons with n vertices for each n>=3. It uses the Poincaré model (the unit) disc to do this. In this model, orthocircles (circles that intersect the unit circle orthogonally) take the role of straight lines.
ifs.zip6k17-01-21File is not ratedIterated function systems
The program uses iterated function systems and the chaos game to create fractals. The user can define and display his own ifs.

The user can construct a graph by entering vertices and edges. The task is then to find the Euclidean minimum spanning tree, that is, a graph without cycles that connects all the vertices and has minimal total length. The Enter key gives a program-generated solution.
netsofacube.zip6k16-03-29File is not ratedNets of a cube
Press numbers 1 to 6 to place colors or numbers into the square grid. Press [Enter]. If the filled squares form the net of a cube, this cube is shown on the right side of the screen. You can rotate it via the arrow keys.
network.zip8k17-08-28File is not ratedNetwork Flow
The user enters a directed weighted graph with a source and a sink (a flow network). The program then computes a maximal flow and a minimal cut.
polygons.zip9k14-11-28File is not ratedPolygons
The user enters points on the screen which are connected by straight lines. Hitting the Enter key then closes the polygon. The right arrow key now constructs a new polygon consisting of the midpoints of the edges of the old one. If the number of vertices is odd, this process is mathematically invertible. This is actuated by the left arrow key.
pythagoras.zip9k15-05-28File is not ratedPythagoras

The program shows the intersection of a torus with the xy-plane. The torus can be moved parallelly to the z-axis and rotated about its three axes.
trammelofarchimedes.zip5k16-05-29File is not ratedTrammel of Archimedes
The trammel of Archimedes is a tool that draws the shape of an ellipse. Two points, A and B, are fixed to a rod by pivots which are confined to move on the x-axis and the y-axis respectively. Any point C fixed to the rod will now describe an ellipse or a circle as A and B move along their axes.
travelingsalesman.zip10k16-04-09File is not ratedTraveling Salesman

ulamspirals.zip10k15-10-23File is not ratedUlam Spirals
A Ulam spiral is a rectangular grid of natural numbers in the plane, starting at the origin and spiraling out counterclockwise in growing squares. If only primes are marked, straight lines parallel to the main diagonals become visible.
voronoi.zip11k16-05-03File is not ratedVoronoi regions
The user enters a set S of points in the Euclidean plane. For each s in S, the Voronoi region of s is the set of points in the plane closer to s than to any other point of S. The program draws the Voronoi regions of the entered points and the corresponding Delaunay triangulation.
wheels.zip6k16-06-24File is not ratedWheels
A small wheel (circle) c of radius r moves tangentially without slipping along the inside or outside of a fixed larger circle C with radius R>r. A point A is fixed to c with distance d to the center of c. As c rolls along C, A describes a curve which mathematicians call a hypotrochoid (if c moves inside C) or epitrochoid (if c moves outside C).
