(Sorry for posting this topic again, figuring it might get to a different bunch if it were posted here too!)

Hi

My gf is having a problems with her disseration, and due to the fact she's not very net-savvy she didn't consider the net an option for finding a solution! So, I'm here on her behalf.

She's doing Accounting, and because I am not all I can tell you is that she's having problems with an equation.

The equation is labelled (1) on page 14 of http://w4.stern.nyu.edu/emplibrary/D...onors_2007.pdf, and the problem is that she doesn't know what 'a' and 'b' mean!

Any help with this would be greatly appreciated!
