HW6 - Q 2 thru 6 - make sure you apply abs() to the last 2 features!

[catherine]

hi everybody, I just lost 4 (!) points because of my printer not being able to properly handle the absolute brackets (||) surrounding the last 2 elements of the transformed input vector (|x1 - x2| and |x1 + x2|). So make sure to double-check any formulas against the online version of the homework instructions. Some of the less usual characters don't print well...
