GeoGebra can be deterministic or continuous one can change it in preferences. All constructions in the deterministic programs GSP, Cabri, Kseg and most of others are completely determined by the given points but the result of some constructions can jump or behave unexpectedly when a given point is moved. On the contrary, some constructions in continuous programs so far only Cinderella and GeoGebra , depend on the number of hidden parameters and in such a way that moving a given point produces a continuous motion of the construction, as a result, if the point is moved back to the original position the result of construction might be different.

## Cinderella

Construct the orthocenter of triangle and three midpoints say A', B' C' between vertices and orthocenter. Construct a circumcircle of A'B'C'. This is the nine-point circle , it intersects each side of the original triangle at two points: the base of altitude and midpoint. Construct an intersection of one side with the circle at midpoint now move opposite vertex of the original triangle, if the constructed point does not move when base of altitude moves through it that probably means that your program is continuous.

Although it is possible to make a deterministic program which behaves continuously in this and similar simple examples, in general it can be proved that no program can be continuous and deterministic at the same time.

Cinderella comes with an easy to learn yet still very powerful functional language. It is designed primarily with the intention to allow for high-level interaction with geometric constructions or physical simulations created in Cinderella.

Nevertheless, it can also be used as a standalone language for performing mathematical calculations. Hint: Use your wand to fend off evil Bogs with the charge attack or to cast magic. Jump — To jump, press the A Button. Interact — Press the Z Button to talk with people and interact with various objects. Cast Magic — Swing the Wii Remote up and down to fend off villains with your magic wand. The Pixie will show you where they are. Each Princess has three chapters.

You can finish one chapter or complete all three before moving to the next Disney Princess kingdom. Remember, you can visit any Disney Princess kingdom in any order you choose.

### Doppelte Zitate

To continue your adventures in the same kingdom, press the A Button. To save the kingdom of a new Disney Princess, go to her alcove. Create Your Own Character Before your journey begins, the Pixie will guide you through the process of creating your very own adventurous character.

Or, add a variety of unique accessories, such as earrings, hats or bracelets. Hint: You can find the character customization screen in the bedroom of Gentlehaven castle, behind the Shirt icon.

Hint: Listen to your Pixie if you need help. She will help you save the kingdoms from the Bogs. You must help Cinderella restore Time and keep her wedding on schedule. Use your magic wand to unfreeze people, animals and objects. Use your courage to help Cinderella restore Time to her kingdom so she can have her fairy-tale wedding. Hint: Pay attention to Jaq and Gus. Only you can help her return harmony to the kingdom. Hint: Use your magic twirl to make sea anemones hide or chase schools of fish.

Watch the schools of fish swim away as you approach. Use that new Color to fill in the world. But is it real? Work with Jasmine and Abu to turn mirages back to normal… …and restore Trust to the kingdom. Each time you are hit by Bog magic, the Pixie Magic Meter will drop. Logo with minimum space indication.

Cinderella comes with an easy to learn yet still very powerful functional language. It is designed primarily with the intention to allow for high-level interaction with geometric constructions or physical simulations created in Cinderella.

Nevertheless, it can also be used as a standalone language for performing mathematical calculations. We first describe those operators that allow to generate conditional branching and various kinds of loops. The user should be aware that there are also other kinds of loop-like structures that arise from the different ways of traversing lists.

They are described in the section Elementary List Operations p. List are among the most fundamental and elementary concepts of CindyScript. In CindyScript lists serve several purposes. They serve as. In addition to its computing facilities, one of the most important features of CindyScript is its powerful possibilities for reading position data from a geometric construction and for direct output of graphics to a construction.

This section is about the output part. One can easily draw points and lines by invoking a graphics operator within CindyScript. It is important to mention that these drawings of points or lines are not geometric objects of the Cinderella construction. Nevertheless, they are extremely useful, since often one wants to create complicated-looking output that is not directly constructible by geometric means.

Then it is often very easy to write a few lines of CindyScript code that generate the output. In particular, CindyScript is very useful if generation of the output requires repetitive application of constructions. One can also use high-level graphics operations within CindyScript to create a plot of a function directly. The geometric operators provide high-level access to several elementary geometric operations. They can be applied either directly to objects of the geometric construction or to vectors lists of numbers that represent the coordinates for the geometric objects.

If the operator returns a geometric object, it can also be directly drawn with the draw operator.
