No, the title and post content is right. I merely replied to your comment that there are no powers in linear algebra.

In course of linear algebra, we are also supposed to find basis for for example: ax^3+bx^2+cx+d. There's also some condition usually, which leads to the solution (like f(1)=f(2), etc.)

nothing much, I've done multiple similar problems with powers of x, but nothing like this. Generally new to the topic. I know that x2=-2*x3-3*x4 and I'm stuck there.

comment Can we keep python & php both with same apache server?
Sorry for misleading, you're right Graham, mod_python is not CGI. As far as I know, it does a little bit more than CGI - embeds itself into the server - but is still outdated and there are new, supposingly better ways to do it.

Ah, so valid XML document has to have root node. Alright, thank you, another thing I simply didn't know.
