Compound Interest Calculation and Demonstration
2016-02-01 13:39
This applet demonstrates compound interest calculations. By inputting principal, interest rate, and periods, it dynamically displays fund growth over time using GeoGebra sequences and lists. It supports bilingual switching, helping users understand compound vs. simple interest and exponential growth in financial math.
