I'm going to wait until LaTeX is fixed again before I go and write the next bit lesson, so it might be a while depending on how long it takes to get fixed

I'm planning to play catch-up this weekend.

Been busy with IHH

...or at some point this week

 

No rest for the me.

Blah, work's no excuse for maths

I played too.

 

[edit] wait a sec; work's no excuse for maths?

Nice layout, like the menus thing. Had to do that the other day to solve an awkward layout issue (on a calendar).

 

Blatently maths > *

 

Cheers

 

What I find hilarious (but also craptastic) is that I have one (count it, one) stylesheet that works for every browser and non-screen device known to humanity EXCEPT for Internet Explorer, which has to have TWO extra style sheets and some js to make it look non-shit.

 

So as revenge the site displays an IE-only message on the front page... heh heh heh.

lol

 

I hate IE with all my guts. Really hope it dies soon

Just some comments on the nomenclature being employed.

 

The differential of a function y = xⁿ for any value of n is n*x^n-1[/sup'].

^{You might want to stick with the word derivative here (i.e. the derivative of a function...) since the word differential is reserved for something else.}

 

^{[math]\frac{dy}{dx}[/math]}

 

^{The first thing to remember is that the "d" is not a variable; it's actually an operator, so you can't simply cancel it from the fraction to give y/x (otherwise things would make no sense). The second thing to notice is the interpretation - spoken aloud it means "the differential (i.e. gradient) of y with respect to x".}

^{"d" isn't really an operator. The operator here is d/dx. Again, the word differential is misused here.}

 

^{I hope my critiques are helpful.}

Fair enough.

 

There's obviously going to be some mistakes in my wording, and I've been misinformed about the operator. But then again I should technically have said "any real value of n". It's unlikely that anyone will really consider the operator side of it.

he's just jealous

 

i, for one, can't wait for the next lesson. cheers!

And why would I be jealous?

oh come now you didn't notice my connotation? it was in more of a joking manner than a serious one.

Next lesson won't be for a while, since I'm off to Ireland for 2 weeks on Thursday.

 

Sorry guys

dave, will there be a new lesson soon? i just went through the first two and can't wait for a new one, yet i see that your last post was last year. could you start it up again?

I have been doing a maths course as part of my current BSc, and the only thing that challenged me so far was validating rearrangements of the limits on the feasible area in a linear regression programming problem. And that was only because it's explained in a craptastic way.

 

So I think I'll be working through these threads again too!

I can start them up again soon if people would like, since I'm on holiday next week

that'ld be great.

So, the next lesson is out (at last)! Closing this thread, all questions should be submitted to the next one.

 

Cheers.
