Hello, what is it's solvation.I tried to solve it by parts but i found undefinable term( from ln(0)).Please give me an advice.Thanks.

the divergence of said integral 1/ln x arises only very close to x=1. At that point log x is basically a simple straight line passing through a zero y=0 with gradient 1 or some finite value or whatever. So the reciprocal 1/ln x shoots off to infinity at x=1 in just the same way that y=1/x shoots off to infinity at x=0. This form of the question looks confusing but really this is a simple integral. Let's rewrite the integral this way: [math]\int {\frac {1}{x}dx}[/math] To anyone who has done elementary calculus, this looks very familiar. Integral of e^x ln(1+e^x) dx? Let u = 1+e^x then du= e^x dx so, Integral of lnu du.

Vtip je v tom, že je jedno co volíš za u a za v, jen je vhodné za to zvolit to, co se dobře derivuje a za u´ nebo v´ něco dobře integrovatelného :-) Hi, I've been struggling with this problem for hours, so I was wondering if someone here could help me out, thanks: The problem is: How to integrate: (ln x)(to the power of 2) Thanks I en gammal tråd om additionsformlerna undrade du vad man skulle med formlerna för dubbla vinkeln till.

I=\underbrace{\int_{1/2}^2 \left[\frac{5}{2}-x\right]\ln x dx}_{I_1}- ut på att man identifierar att man ska integrera en produkt av två funktioner.

Setting u(this is the variable that is differentiated and may differ depending on where you study) as ln (x) what is the integral of ln(x).

(I'll bet that derivative formula is somewhere in your text.) Since d(2 x)/dx= ln(2) 2 x, the anti-derivative of 2 x is (1/ln(2)) 2 x.
