This book is from Lial, Greenwell and Ritchey. My Calculus class requires the 9th edition but I know from past experience that some of the books are the same the only difference would be the years. And I also know sometimes things do change. Can anyone confirm that this book is the same word for word as the 8th edition? It would save me a lot of money if I am able to use the 8th edition instead (Happy)
i am pretty sure they are. especially when the editions get that high, 8th or 8th edition, nothing much changes. in anycase, the only problem you may have is the the pages may be numbered differently, as well as the problems. so your professor might say your homework is #4 on page 50 when in your edition it might be #2 on page 51, so be aware that you may have to tackle things like that. but as far as learning a topic from the text is concerned, there should be no difference.Quote:

When I took intermediate algebra I thought I could save some money by buying an ealier edition. That turned out to be a pain due to either more problems were added or remove making every question out of order. I'm willing to take a chance and buy the 8th edition hoping everything is still numbered the same as the 9th edition.
I know calculus books usually don't change that much. i ahve seen the 4th, 5th and 6th edition of a calculus book that i used and nothing much changed. even the problem numbers were the same. they just added some more graphics and stuff. isn't there a way for you to compare them? where are you buying the 8th edition? where is the 9th sold?Quote:

haha, yup. is $115 worth the possible headache of (probably) having to copy a problem or two from my friends. to me it is!Quote:
