William Haynes on V-M 5a: Arbitrary parabolic loading 2 years, 6 months ago

Saved a checkpoint:

State prior to testing. Uses a variable callling a javascript function.

○

William Haynes on V-M 5: Symmetric parabolic loading 2 years, 6 months ago

Saved a checkpoint:

Currently using the javascript function

Saved a checkpoint:

This demos the problem. Three methods of loading a ggb applet compared.

1. uses javascript function Most complicated method, but reloads and can call click script to rescale

2. Defines a variable. Doesnt reload, can't call click script to rescale

3. directly loads geogebra_applet() Reloads, but can't call click scripts or get values from the applet

William Haynes on V-M 5: Symmetric parabolic loading 2 years, 7 months ago

Saved a checkpoint:

Tried to revert to geogebra_applet() method with parameters, but couldn't make it work. Restoring to previous version... geogebra_function() attempt.
