cable cars
Our task (given from the Latvian team) was to construct a mooving cable car with Geogebra. There were different realisations. It was really difficult to find out how we can use a Picture from a cable car. by this we learnd how to use GIMP to free the cable car in the photo from ist Background. For those who run on a not-linear cable help from the teacher was needed. students don#t know at that age nothing about the math of conics and quadratic functions. Version 4 was made by the teacher.
