Re: Minimise the distanceHi; 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. #3 20130326 22:00:59
Re: Minimise the distanceHow to do it? 'And fun? If maths is fun, then getting a tooth extraction is fun. A viral infection is fun. Rabies shots are fun.'

Re: Minimise the distanceFor one thing always have a rough idea what the answer is. Sometimes you can have the exact answer before you even start with the the mathematics. 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: Minimise the distanceI believed it would be the midpoint 'And fun? If maths is fun, then getting a tooth extraction is fun. A viral infection is fun. Rabies shots are fun.'

Re: Minimise the distanceA drawing also helps. Calculus will give an exact answer but geogebra got the answer to 15 places! In mathematics, you don't understand things. You just get used to them.

Re: Minimise the distanceI used geogebra. But .... I couldn't find the exact 'And fun? If maths is fun, then getting a tooth extraction is fun. A viral infection is fun. Rabies shots are fun.'

Re: Minimise the distancey = 6.6 is the answer that geogebra comes up with. Can you do that? 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. #9 20130326 23:00:20
Re: Minimise the distanceSo to minimise it we find its derivative f' 'And fun? If maths is fun, then getting a tooth extraction is fun. A viral infection is fun. Rabies shots are fun.'

Re: Minimise the distanceYes, that is how calculus would do it. Again, I would urge you to graph the function first to have some idea where the minimum 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.

Re: Minimise the distanceI haven't got an idea to find the derivative except using a CAS. 'And fun? If maths is fun, then getting a tooth extraction is fun. A viral infection is fun.

Re: Minimise the distanceYes, sorry about that. My excuse is that I was being harassed by the slow reload time on pages. It was driving me mad. Originally I just posted the method. Then I had the idea to work out the answer but hide it. But I was completely off track because I had been thinking that 'y' divided the line in the ratio a:b ie 2:3 so I posted a + b = 5.
