How Domain Restrictions Can Help Students Model in GeoGebra Augmented Reality
- Tim Brzezinski
GeoGebra Augmented Reality allows users to input many domain restrictions on multivariable functions! Note the equations of the 2 surfaces shown in the screencast below (at bottom of screen). The blue surface is a paraboloid of revolution for which . The pink surface is part of a parabolic sheet for which . Put together, these 2 surfaces are used to model the coffee filter shown at the end of this screencast. You can enter AS MANY DOMAIN RESTRICTIONS within GeoGebra Augmented Reality as you'd like.
