Printing Errors in "Engineering Mathematics 7th ed - K.A. Stroud, Dexter J. Booth" !

I purchased this book few days ago from an eBay seller for a fairly cheap price. I saw a printing error on the 1st page of the "Useful Background Information" section (page xxv). Under the subtopic "Trigonometric identities", my book just says "....^2 theta = 1 + cot^2 theta ". The cosec part is missing!

I just want to make sure whether it's just an error all the books have. Not just in mine. Considering the place I bought it, it could be a crooked copy! And I don't want to be misled. So if you have a copy of this book, please check, and let me know.

What is the book's ISBN (given on page ii)? Google's preview of the 7th Edition paperback doesn't have that printing error.
