This application is a tool for the visualization of hierarchical planar curves. A hierarchical planar curve is defined as the path followed by a stationary point within one planar coordinate system which belongs to a hierarchy of relatively-moving planar coordinates systems. In a hierarchy of relatively-moving planar coordinate systems, each system moves in reference to exactly one other system.
With a series of mouse clicks on various graphical controls, a user can

| Description: |
The best way to summarize a mass of numerical data is to use a simple equation. To develop that equation, you need graphical and equation fitting tools. EqFit v3.0 gives you these tools to build and test trial equations against your data using standard calculation methods from the Statistics field. The Statistics menu provides two methods to fit equations to data. Use the Regression Workbench menu to perform Multiple Linear Regression with up to ten dependent variables. You can build hundreds of different equations in the Workbench by transforming individual variables in ten different ways. For example, in Chemistry, the equation for vapor pressure is well known and can be readily built in the Workbench. A chemist with vapor pressure vs. temperature data for a compound can find the equation constants by fitting the data to the known equation set up in the Workbench.

Equation Grapher v1.20 is a function plotting/analyzing program. It allows you to draw graphs like y=2x and y=sin(x+10)-cos(3x). It is possible to have up to 13 graphs plotted at the same time. Once you have plotted a function, Equation Grapher automatically finds roots, maximum/minimum, intersections, etc. It also calculates and views integration area. If you like, you can copy the graph and paste it into your word processor. Of course, it is possible to save your work and continue at another time. A pedagogical help file with descriptive pictures is included. |

| Description: |
NonEuclid is a Software Simulation offering Straightedge and Compass Constructions in a Non-Euclidean in geometry called Hyperbolic Geometry (a geometry of Einsteins General Relativity and Curved Hyperspace). NonEuclid is designed for use in High School and Undergraduate Education. NonEuclid also provides a thorough, introductory explanation of Hyperbolic Geometry, with over 25 pages of illustrated hypertext. Some of the reasons why it is important for high school students to study Hyperbolic Geometry are: 1) Hyperbolic Geometry is becoming increasingly important in its roll in modern science and technology. 2) A study of Hyperbolic Geometry make clear that geometry is not something that was completed 3,000 years ago in Greece. Geometry is a current and active field of research. 3) "Definition" has a precise meaning in geometry that is quite different from its meaning in common language. Confusion on this concept is the source of many difficulties students have in understanding geometric proofs. The strangeness and counter-intuitiveness of Hyperbolic Geometry helps students to perceive the subtle, yet critical, differences between "Definitions" and "Theorems" as they are used in geometry. |

| Description: |
KwikTrig is a useful program for students, machinists, tool and die makers, engineers, and perhaps even astronomers. Runs on Windows 3.x, Windows 9x, Windows NT 4, and Windows 2000. It takes complex trigonometric problems and automatically solves them with the most minimal input from the user. KwikTrig has solutions to right triangles, oblique triangles and bolt hole circles. All solutions to triangles graphically display the relative shape of the triangle in proportion to its size. Solutions to triangles allows user to enter/display angles in decimal degrees and or d/m/s. Solutions to bolt hole circles also displays the position of all holes and indicates which one is the primary hole. A textbox displays X, Y coordinates for each hole and the chordal distance between the holes. All solutions allow the user to round answers from 1 to 15 decimal places and can send input to the printer. |

mlyn106a.zip (Aug 7 1997, 1.7M) |
| Description: |
Merlyn is able to create mathematical expressions that look as if they were in a textbook. There is also the ability to manipulate those equations. If you look at a problem that has been done step by step in a textbook, the difference between one step and the next is that some part of the expression has been rearranged, simplified, canceled, and so on. This is just what Merlyn does. Select the part of the expression you want to change and then apply commands like simplify, cancel, commute, etc., and the expression changes accordingly. If there is more than one possibility you are offered a list of options. Pick the one you want and the result appears in your document. Use Merlyn for algebra, trigonometry, calculus, and the physical sciences. Educators can use Merlyn to create class materials. |

Oriana for Windows v1.0 calculates the special forms of sample and inter-sample statistics required for circular data (e.g. directional data or time of day). It also graphs your data in a variety of ways, allowing you to easily demonstrate patterns. Oriana calculates the circular mean, length of the mean vector, circular standard deviation and standard error, 95% and 99% confidence limits, and Rayleigh's test of uniformity for each sample in your data file. Pairs of samples can be compared with Watson's F-test for two circular means. The overall distributions of two samples can be compared with Chi-squared tests. The data for each sample can be summarised with rose diagrams or circular histograms as well as linear histograms. The individual observations can be shown in raw data plots. Uniformity plots allow you to assess whether the data depart from a uniform distribution. |

Solutions is mathematical software built for engineers and scientists. It is powerful yet easier and more flexible to use than your standard or your RPN calculator. Solutions will provide you with 20 classes of function from Algebra to Statistics. It will plot and print your work. You can even program it if you need more power. Solutions will do quick work of your calculations. All Solutions' functions work with both symbolic and numeric data. Numeric data can be real or complex numbers, as well as vectors and matrices. You work interactively with Solutions as with a calculator (but it is much more powerful) so you will use it within minutes. Solutions fully supports algebraic computations. For example, you can instantly compute the derivative of any equation. The answer is given to you directly or one step at a time so you see all the intermediate results. Should you need it, Solutions' programming language is simple to learn and will provide you with even more power for solving complex problems. It is a much quicker and efficient alternative than Fortran, Basic or C. |
