Why this LaTeX typing doesn't display?

[mcastillo356]

Hi PF
I've been for a while taking a glance to recent posts of mine, in search for right or wrong LaTeX performance; everything correct, except for this thread:

https://www.physicsforums.com/threa...n-understanding-different-approaches.1056106/

The following typing has not worked

$$=\frac{1}{2}\ln{|u-1|}-\frac{1}{2}\ln{|u+1|}$$

Where is the mistake?

Regards

What equals?

$$x=\frac{1}{2}\ln{|u-1|}-\frac{1}{2}\ln{|u+1|}$$

You cannot use colors in formulas.
