Geometric Meaning of k in Inverse Proportional Functions

2020-07-10 12:27
This GeoGebra applet demonstrates the geometric interpretation of parameter k in the inverse proportional function y = k/x. The key property is that for any point P on the curve, the rectangle formed by dropping perpendiculars from P to the x-axis and y-axis has an area equal to |k|. The construction features interactive input boxes and buttons, allowing users to drag point P or adjust k to observ
