Hi all,

In this true or false?

(5/2)ln(1-2x)-2ln(x) = -2ln(x)+(5/2)ln(2x-1)

Hi all,

In this true or false?

(5/2)ln(1-2x)-2ln(x) = -2ln(x)+(5/2)ln(2x-1) - Jun 29th 2011, 05:39 PMKrizalidRe: True or False?
$\displaystyle a-b=-b+a,$ it's true, haha. :D

Oh, I misread it, I thought it was $\displaystyle 1-2x$ on both sides.

One of them is the correct result of an integration using partial fractions. For some reason (I don't know) some of the results are in this form -2ln(x)+(5/2)ln(2x-1) however the first one: (5/2)ln(1-2x)-2ln(x), note there is a pattern (2x-1) instead of (1-2x).

This was for the integration of:

(x+2)/(2x^2-x)

Is there something I need to understand here? - Jun 29th 2011, 05:58 PMKrizalidRe: True or False?
Remember to put absolute value to the logarithm.
