I know to move the (1/2) up to (2/4) for like denominators, but I'm totally lost as to what relation (-9/4) has in to the now (2/4) and (3/4) and how any of that turns into (2/13) and (3/13). The only relation I see is that 9+4=13; but that doesn't make sense in my head.
The one I'm currently working with had e^7x and cos(6x); so my current fractions are (7/49) (6/49) and the I of (36/49).
Is the odd relation of 9+4=13 therefore new denominator magically becomes 13 correct? Or is there some gypsy magic way to solve this easier?

Ok, so that (a/b) into (a+b)=denominator magic works. Can anyone tell me why? I'm sure it's really simple, but for some reason, I just can't wrap my head around it.
[QUOTE=Aathma;39295134]Did you try solving for 'I'? It is pretty obvious that when you move the (-9/4) I to the right side you get (1+9/4) I or (13/4) I. You then divide both sides by (13/4)...[/QUOTE]
I... never even though of it like that. As in seriously, I haven't. I have a really hard time visualizing some things in math, and other things turn out very easy.
Thanks a ton for that!

This is why I went to a game design school.
