How to integrate these? :(
Hello!

I have attached a document, which contains two functions, which i ain't able to integrate myself. Please explain me how to do this.

Advice: use another kind of file. Many here (among them, I myself) won't open an unknown .doc document.

Nevermind. I discovered that the proportion between the integrals was y=0,25*x^-1 - Two very complex integrals turned into a very easy thing.

EDIT: What kind of file should I be using? and Do you know a program which is always able to show the integral as a function? - unlike Ti-interactiv.

$\int dx$

double left mouse on the formula to see how to write it ...

I suppose that a PDF would be much less dangerous to open. If you are running Windows you can convert your Word document to PDF with PDFCreator (http://sourceforge.net/projects/pdfcreator/)

Just disable script in word and you are safe or has windows gotten that insecure. Here I exported the two equations as pdf using the power of linux (Cool) Attachment 18331

The second one looks like an elliptic integral. I don't think the firs one can be solved.
