College Algebra  Volunteers WantedI have just completed a large project ... my complete College Algebra course. "The physicists defer only to mathematicians, and the mathematicians defer only to God ..."  Leon M. Lederman #2 20100417 13:34:14

Re: College Algebra  Volunteers Wantedthat's pretty interesting! If two or more thoughts intersect with each other, then there has to be a point. #6 20100417 18:30:52
Re: College Algebra  Volunteers WantedHi MathsisFun;
I like the idea of numerical experimentation as a means of getting an answer that can later be proved rigorously. 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. #7 20100417 19:30:14
Re: College Algebra  Volunteers WantedThanks. And good point. Maybe I should throw an odd one in. "The physicists defer only to mathematicians, and the mathematicians defer only to God ..."  Leon M. Lederman #8 20100417 19:37:13
Re: College Algebra  Volunteers WantedThe decomposing the cube into 4 cuboids was really cool. So far, so good.
You could include "or both."

Re: College Algebra  Volunteers WantedHi MathsIsFun,
What I said in my other post:
In the first example, INT(3.65) = 4, while in the second INT(3.65) = 3. "The good news about computers is that they do what you tell them to do. The bad news is that they do what you tell them to do."  Ted Nelson #16 20100420 07:17:17
Re: College Algebra  Volunteers Wanted
Oh yeah. How about this: "The physicists defer only to mathematicians, and the mathematicians defer only to God ..."  Leon M. Lederman #17 20100420 15:14:00
Re: College Algebra  Volunteers WantedHi MathsisFun;
Maybe not entirely true. Depends on how costly the first error you make is. 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. #18 20100421 00:48:03
Re: College Algebra  Volunteers Wanted
I reckon this might be better:
I'd prefer this, which I think ties it in more clearly with the part that int plays in this: Last edited by phrontister (20100421 10:47:22) "The good news about computers is that they do what you tell them to do.

Re: College Algebra  Volunteers WantedHi MathsisFun; This is read ph =  log of the molar concentration of the hydronium ion (or hydrogen ion). Confusing because in chemistry the [ ] have a specific meaning. 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: College Algebra  Volunteers Wanted
What do you recommend I change? I don't want to be inaccurate. "The physicists defer only to mathematicians, and the mathematicians defer only to God ..."  Leon M. Lederman #22 20100421 12:02:17
Re: College Algebra  Volunteers WantedHi; So when [H+] is 10^(7) then  log (10^7) = 7 a neutral ph. As [H+] goes up [OH] goes down. You can use either of these for accuracy. Use either of those just as long as in your opinion it does not confuse the reader. Just phrase it as  log of the molar concentration of the hydronium ion or the hydrogen ion for H30+ or H+ respectively. You see in math [ ] is for grouping but in chemistry [ ] this means molar concentration( moles per liter ). In mathematics, you don't understand things. You just get used to them.
