Expected distance and geogebra.Hi; In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #2 20130610 12:12:41
Re: Expected distance and geogebra.Could you please enlighten us with the analytical solution? 'And fun? If maths is fun, then getting a tooth extraction is fun. A viral infection is fun. Rabies shots are fun.' 'God exists because Mathematics is consistent, and the devil exists because we cannot prove it' 'Who are you to judge everything?' Alokananda #3 20130610 15:31:20

Re: Expected distance and geogebra.Hi, Code:samp =: 100000 (+/%#)((((?samp$0)(?samp$0))^2)+((?samp$0)(?samp$0))^2)^%2 A result I got ≈ 0.520588 "Believe nothing, no matter where you read it, or who said it, no matter if I have said it, unless it agrees with your own reason and your own common sense"  Buddha?

Re: Expected distance and geogebra.It's fast to code in it only when you have a certain proficiency with it. Otherwise it takes a lot of time looking at the glossary for each individual character. I am guessing you've been using J for a while then?

Re: Expected distance and geogebra.That's right, we must know the glossary first.
