Change your subject.Make k the subject. #2 20130805 05:04:43
Re: Change your subject.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. #4 20130805 08:36:25
Re: Change your subject.I'd say it's: Or maybe with k and p both in the denominator.

Re: Change your subject.hi Stefy, Ebenezerson: That looks a bit like what you had. But k is not yet the subject. We must deal with the square root: Hope that is what you were wanting. note: You must not just invert all the fractions to get Try with numbers: Bob You cannot teach a man anything; you can only help him find it within himself..........Galileo Galilei #6 20130805 22:37:04
Re: Change your subject.The 'k' squared plus the 'p' squared are on one platform, which is over the 'hg'. #7 20130805 22:49:27
Re: Change your subject.
"equal to sign" and after the sign, there is a "negative or positive sign" which confound me much. #8 20130805 23:00:35
Re: Change your subject.I am curious, which answer did you like? 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.

Re: Change your subject.
But the book has 1/n and a negative or positive sign after the "equl to sign", which is incomprehensible to me. Some help. #10 20130805 23:35:28
Re: Change your subject.Is post #4 the right problem? 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. #11 20130805 23:53:05

Re: Change your subject.Bobbym, I cant found them at the bottom of the open window. There are few that are found there. #15 20130806 00:34:57

Re: Change your subject.the 'n' at the bottom carries a square why didnt you bring it? #19 20130806 01:21:21
Re: Change your subject.Sorry, I am not getting an n^2 just an n. I had Mathematica do that and he is never wrong. In mathematics, you don't understand things. You just get used to them.

Re: Change your subject.If we take it from the start. the n has to be squared when the square root at the R.H is taking away. #21 20130806 01:35:15
Re: Change your subject.But, when you clear k of the square, you will be taking a square root, which means n will lose the square.

Re: Change your subject.Yes, the n^2 will disappear. 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. #25 20130806 01:44:59
