• Resumen

  • GeoGebra is an extremely powerful tool for mathematics teaching and learning. We share how to create a GeoGebra worksheet that can be used to display dynamically changing quantities. This worksheet can support students as they make meaning of the inverse cosine function. First we share some mathematical background. Next we provide detailed instructions for creating the GeoGebra worksheet. We conclude with a sample student response to illustrate how students might reason and learn using a GeoGebra worksheet.
