﻿ Casyopee - Casyopée’s four tabs

What they say:   I used Casyopée to help students solve optimisation problems. It allowed me to present students very open tasks. Students explored and found results that they had to prove afterward. Casyopée also helped students reuse basic strategies for solving.
What they say:   Casyopée is faster and more convenient than a calculator.... We have the geometric and algebraic side of the problem at the same time. It is easier to see how a function "reacts." It's useful and interesting.
What they say:   Casyopée makes it easy to calculate a derivative, to factor, to calculate zeros... and have a graph of the function next to it in the same window. It allows on a geometric problem to be able to establish variables that can then be used to study the problem by way of functions...
What they say:   Casyopee is a powerful application that can prove useful to both students and teachers It allows you to use various exploration and modeling tools, with the purpose of studying or teaching mathematical functions.
What they say:   Casyopee comes with lots of features. One of these features is the help provided for proving a function. There is also a feature for writing HTML reports that include the mathematical functions. Casyopee is guaranteed to improve the mathematical knowledge of its users.
What they say:   Besides the concept of number, the concept of function is the most important one in mathematics
What they say:   The notion of function is present in all scientific disciplines, and also in everyday life. Our experience as a teacher shows every day that it is a problem for many students. Situations with Casyopée can also be used outside of a technological environment and everyone will be able to reflect on her professional practice.

Figure 1 – Algebra and graphic tabs in the Casyopée window

With the  button, the algebra tab (expression list, and optionally X-values, functions and equation lists) is switched with the dynamic geometry tab. The  button allows the reverse action. The graphic tab is switched with the geometric calculation tab using the  button. The reverse action is done via the  button.

Figure 2 - Geometric tabs in the Casyopée window

Notes:

Using the buttons Algebra/Geometry and Graphs/Geometric calculation, four main configurations are available.  Figure 1 and Figure 2 above display two of these.

In a configuration "Geometry and Graphs" ,dynamic figures in the geometry tab can be animated together with graphs.

In some cases, it is useful to see both the algebra and the geometry tabs. This is done by “detaching” the geometry tab.

The NotePad is always visible and “hides” the Graphs/Geometric calculation tab when in full page mode. The “hidden” tab can be made visible by unchecking the corresponding item in the NotePad menu

Starting Casyopée, the Algebra tab is displayed with just the expression list and the NotePad in full page mode.  The graphic tab is hidden behind. The version number is displayed on the initialisation form, and after that in the NotePad. If the computer can access the Internet, it is possible to check whether a new version is available via the Check New Version button. If there is one, automatic update will be proposed. This button is available on the initialisation form, and after that on the about form available through the ? menu. This manual is up to date for version 3.1.4. Working with the newest version is recommended.

More help is available through the help (?) command of the menu bar. This getting started manual refers to Casyopée's menu entries. Using buttons associated with the commands (see p. 38) is also possible. The entries are written in bold font. Between two exercises, you can do Files / New and you will be prompted to save your work. You can also run another instance of Casyopée in order to carry out two tasks in parallel by Files / New Window.  Casyopée’s calculation uses Maxima, an open source piece of software for symbolic computation: http://maxima.sourceforge.net.
