- Author:
- Sangeeta Gulati

This workbook was created for the workshop "Create , Visualize & explore with GeoGebra and Desmos" for secondary and senior secondary mathematics teachers conducted on November 27 & 28, 2015. This workshop was held at Sanskriti School , New Delhi, India and led by Sangeeta Gulati. Over the past years, I have created and curated many other useful applets related to CBSE curriculum for use of teachers and students.
