Random Functions
Selecting a random function out of 10 with a button A simple file to answer Hillary Einsiger's request. I created 10 functions, put them in a list and then choose f=Element[list1,k] The button has a script k=RandomBetween[1,10]
I figured out how to make buttons to start and stop an animation, but I couldn't figure out how to consolidate them into one button. Is it possible? June (7/14/11 11:30 CST)
I got an answer to this on the forum. Here it is:

a is your slider to animate
b=-1
c=if[b==-1,false,true]
Then your button script is
StartAnimation[a,c]
b=-1 b

Thanks, June - Mike and I figured out something equivalent after the session (I just saw this). We essentially get rid of the need for the c and if statement here, and use subtraction instead of multiplication for the switch. I posted an example (ToggleButton) on the Instructor Applets page -- Russell (7/14/11 6:53 PM CDT)
Can Mike May post the applet he created in this morning's class, so that we can figure out what we missed and try to fill in? -- Elisse (7/11/11 1:30 CST) NEVER MIND, I see that it is posted on Instructor applets
