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.   A teacher
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.   A student
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...   A student
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.   Softpedia
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      David Hilbert
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.   A university teacher

How to attach an image in the geometry window of Casyopée

In order to properly position the image, it is useful to create a fixed point (coordinated point) How to attach an image to a point in the geometry window Casyopée

Here we attach an image of the Statue of Liberty, which reaches a height of 93 meters.

Thus we position a point (0;93)

We use the Zoom Out tool

and we zoom to reveal the show the origin and the fixed point.

We could also use the mouse (Ctrl Scroll down)

We choose to attach the image to the origin.

Right click on this point for the contextual menu. Choose "attach an image."

A file selection box opens. Graphic format files are available.
The image is placed with its lower left corner on the selected point.


Right click on the image provides access to its properties.

You can choose a magnification to adjust the image's size and an angle..

This is the picture well framed.

By attaching a picture to a free point on segment or circle and assigning a speed for this point, you create an animation.

To create an animated gif, use the menu File Save screen.


Attach an image to a segment

Like for points, Right click on a segment for the contextual menu. Choose "attach an image."

The bottom left of the image is placed on the first point. The bottom right is place one the second point.

The image follows the segment when one of its end point moves.
Like for points, you can stretch and turn the image by the property contextual menu entry.
