Summary
[edit]DescriptionLeiterstellversuch (Δx, Δy).webm |
Deutsch: Eine Leiter wird an eine Hauswand angelehnt. Das kleine x steht für die Entfernung des Leiterfußes von der Hauswand. Das kleine y steht für die Höhe des Anlehnpunktes der Leiter über dem Boden. Eine Funktionale Beziehung y=f(x) zwischen x und y ergibt sich über mit die Länge der Leiter (hier etwa 14 cm) mit dem dem Satz des Pythagoras. Die explizit nach y umgestellte Funktionsgleichung ergibt dann eine Wurzelfunktion.
Das Video zeigt, was die Terme Δx und Δy in dieser Anordnung anschaulich meinen: Δx steht für eine Änderung des x-Wertes, Δy für die dazugehörige Änderung des y-Wertes. English: A very simplistic experiment to demontrate the practical meaning of Δx and Δy as changes of values. A ladder is set up against the wall of a house. The ground, the wall and the ladder then form a right triangle. With x as the distance of the ladder from the wall measured on the ground and y the height of the upper part of the ladder where it touches the wall, one can build a mathematical function y=f(x). |
