Query: It's No Good

Whoever printed this book did a terrible job. The greek symbols are consistently missing so unless you already know the formulas you will be lost. I wish I could get my money back, but by the time I figured it out, it was too late. If you are an instructor, please do not make your students use this book. I guess the content would be fine if it weren't so confusing with the formulas.
