Mathematics has always played a central role in secondary school curriculum in Denmark. The Danish Ministry of Education continues to emphasize its importance as it mandates reforms and new standards that students are expected to meet in order to graduate. The country’s high standards of mathematics have led to the adoption of Maple in 110 of 160 Denmark high schools. Maple is a software tool from Maplesoft that makes it easy to explore, visualize and solve problems in mathematics.

The worksheet shows a procedure for the representation in de Poincaré disc of convex and self-intersecting regular hyperbolic polygons.

The worksheet shows a procedure for the representation in de Poincaré disc of regular right-angled, convex and star hyperbolic polygons.

In the present worksheet is shown a procedure to obtain the relations for the sides and angles of a hyperbolic polygon, no matter its number of sides. The study consists of two parts, the first for polygons in general and the second for right-angled polygons in particular. The results can be applied, for instance, to the construction of hyperbolic polygons. For that, the required number of data is 2p-3, p being the number of the sides of the polygon.

The physical effect known as stepwise precession is a surprising fact that takes place in the movement of an elastic pendulum. When this pendulum is initially set near the downward equilibrium vertical configuration, with the length of the spring stretched by the gravity force, there is a chance to move in such a way that the springing vibrational mode of movement and the rotational "swing" mode interchange periodically their respective energies, with a periodic change of the swing plane and stepwise precession. We simulate here numerically the same dynamical behaviour for the natural extension of a double elastic-spherical pendulum.
