Undocumented Features In 4.0

I was poking around the Wolfram Research FAQ web pages and went to http://support.wolfram.com/Kernel/Symbols/Developer/index.html and http://support.wolfram.com/Kernel/Symbols/Experimental/index.html There I found what looks like lists of all symbols in the Experimental and Developer contexts. Several of the symbols listed there aren't documented in the Help Browser, but I was able to figure out how to use two of them. Below I demonstrate two of these undocumented features. I couldn't figure out any of the other undocumented symbols listed at the above URLs. If you can figure them out please let me know. > In[1]:= > Developer`ContextFreeForm[aaa`x+bbb`y+z] > > Out[1]= > x+y+z > > > In[2]:= > Experimental`Infimum[11+6 x-10 x^2-5 x^3+2 x^4+x^5,-2<x<2,x]//InputForm > > Out[2]= > Root[-69847 - 171468*#1 - 129054*#1^2 - 24692*#1^3 + 3125*#1^4 & , 1] > > -------------------- > Regards, > Ted Ersek > > Download Mathematica tips, tricks from > http://www.verbeia.com/mathematica/tips/Tricks.html >
