Barbara, This book is full of equations that aren't going to work out, I think. I asked Jim in Michigan, who scans lots of non-fiction books, and he said that he could try to scan the book but it would also be without the equations. I recognize some parts of the equations from a calculus class. Is this the book you thought you wanted?
