Mathematical Models

Mada an "introductory" page on Mathematical Models

How do you like it?

Re: Mathematical Models

I really like this page. I think the example is a very good one, because it demonstrates that when improving a model, there's a point where the next thing that needs considering would make the calculations much more complex and the accuracy is already good enough that it's probably not worth doing.


Why did the vector cross the road?
It wanted to be normal.

Re: Mathematical Models

Hi MathsisFun;

Interesting, except the part about having a job for life. That was depressing.


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.

Re: Mathematical Models

The page looks great. I just have one question. How did you figure out the minimum (0.22, 0.17)?

It's also possible to use calculus to get the exact answer - the x-value turns out to be

Re: Mathematical Models

Thanks, everyone!

Yes, I just eyeballed it, as the exact solution is a calculus thing. I might mention that on the page.
