# Instructor applets

A page for applets by the workshop leaders

Mike's:

• Preparatory - Some applets for examples of applets pages in the wiki.
• Monday morning - This morning we looked at a the Side Bisectors of a triangle.  We looked at creating a  ggb file and an html file.  Both can be uploaded and linked to from a page, so others can use them.
1. will produce the html page.
2. SideBisectorMKM.ggb gives the file
• Monday afternoon -
• Tuesday Morning - We looked at some of the user interface differences with release 40 of GeoGebra.  We then looked at some example applets
1. morning1.ggb  We started looking at a translation of the sine curve
2. Morning2.ggb We then looked at the function analyzer
3. We looked at  , an applet that used fuctions of two variables
4. We also looked at   which has three applets on the same page.
• Tuesday Afternoon
• Wednesday Morning- We started talking about scripting
1. We looked at the applet for dividing a segment by ruler and compass construction to look at stealing applets.
2. We looked at the family of functions applet to see an example of javascript.
3. For this afternoon we will look at a file without ggb script and add the scripts so we can get rid of the algebra window. We will work with the file in SlopeFields(1).ggb 4.0.
4. Some examples form the web of ggb files with scripts.  Some examples are mutually_exclusive.ggb and counter.ggb .
• Thursday Afternoon - Some fast fiels that were demonstrated
1. An applet for doing a proof of the Pythagorean theorem Pythagoras.ggb
2. An applet for asking the student to find a randomly chosen point and noting when it is correct. RandomQuiz.ggb
• Friday Morning
1. An applet to look at a toggle to start/stop animation AnimationToggle.ggb
• Friday Afternoon

Russell's:

• Monday afternoon - An applet using algebra tools
1.  contains the applet in a web page
2. QuadraticsRDB.ggb  is the GeoGebra file
• Tuesday afternoon - unit circle parameterization and spreadsheet features
1.    contains the unit circle applet in a web page
2. UnitCircleRDB.ggb is the GeoGebra file
3.  contains the spreadsheet with statistical features in a web page
4. SpreadsheetStatsRDB.ggb is the GeoGebra file
• Wednesday morning - a collection of applets for calculus
1.  contains the applet exploring some derivative tools
2. Derivatives.ggb  is the GeoGebra file
3.  contains the applet demonstrating Taylor polynomials
4. Taylor.ggb is the GeoGebra file
5.  contains the applet exploring Riemann sums and integrals
6. AreaSums.ggb is the GeoGebra file
7.   contains the applet for sequences and series
8. Series.ggb is the GeoGebra file
• Thursday morning - matrices in GeoGebra 4.0 and some image manipulations

(Note that I had trouble getting the applets that use GeoGebra 4.0 features to save as html pages,

so the html pages that are here were created in GeoGebra 3.2)

1. Matrices in GeoGebra 4.0 -
2. Image manipulations - attaching images to points and moving them.
1. ButterflyOnCurveRDB.html contains the applet
2. ButterflyOnCurveRDB.ggb is the session ggb file (opens in 3.2 or 4.0)
3. ButterflyOnCurveButtonRDB.ggb adds buttons that control the animation (GeoGebra 4.0 only)
3. Geometric transformations of images (and other objects)
1. FrogTransformationsRDB.ggb is the GeoGebra 4.0 ggb file (includes ApplyMatrix, a 4.0 only command)
4. Tessellations
1. FishTessellationRDB.html contains the applet
2. FishTessellationRDB.ggb is the GeoGebra file (opens in 3.2 or 4.0)
• Thursday afternoon - we figured out a way to implement a toggle button for starting and stopping an animation (this could easily be adapted for other uses) using a binary integer-valued variable:
1.  contains the applet
2. ToggleButtonRDB.ggb is the ggb file
• Friday afternoon - implicit functions (can't seem to get the html version to load)
1. Implicit.ggb is the ggb applet
