Google Print saves my butt 

I could have figured it out pretty quickly, but I wanted to look up a quick transformation on a cubic (given y=x^3+ax^2+bx+c, was it X=x+a/3 or X=x-a/3 which makes the x^2 term vanish). I knew exactly where to find it in Needham's Visual Complex Analysis, but the book was at home and I was at school. I try google print, and sure enough Needham is in there and with a quick search on "inflection" I had my answer. How convenient.
