Oct 24, 2014 at 16:03 comment added egreg I'd move also the 2\sigma_{2,1}\sigma_{2,3}\sin(x_{1})u term to the next line.
Oct 24, 2014 at 16:02 comment added user11232 @barbarabeeton Eh, yes. I corrected and going to sleep now (which is the right thing to do for now) Thanks.

Oct 24, 2014 at 15:56 comment added barbara beeton what i think has happened here is that the change to get a unary minus in the second line was not back-edited into the code; that's why the extra space when you use the code i quoted in my comment. if that's really the case, then please fix the code that's shown.

Oct 24, 2014 at 15:54 comment added Manuel As barbara says, I think in case you are not trying to align anything, then \quad or \qquad is enough. But that's just a “matter of taste” :)
Oct 24, 2014 at 15:47 comment added barbara beeton not sure why you've used a \phantom at the beginning of the third line when \qquad would probably do as well; if it's really meant to line up the plus just inside the opening bracket, then repeating the string from the previous line, as \phantom{{}= - \bigl[}, would be more appropriate.
Oct 24, 2014 at 15:40 comment added user11232 @Manuel I missed that one. Thanks for noting and corrected.

Oct 24, 2014 at 15:37 comment added Manuel The last line + is a unary operator, I would convert it to a binary operator; even if there's nothing before on that line, there is in the expression.
