I have had to use cengage for my math textbook this semester, and it has been very frustrating. The pre-calculus textbook for some bizarre reason, only has answers for every other question, which makes it useless for learning generally unless you go and check your answer another way. The answers also just say what the answer is, and don't make an attempt to explain why or how, which is annoying. While I'm not sure if that's cengages fault or not, I do know that it is their fault that I get signed out upon leaving the page I'm on every time, and have to sign back in. It's a MATH TEXTBOOK of course I'm going to be on one page for a long time. Overall, genuinely the worst online textbook I've ever used, and has caused me hours of anger.Edit:Alright its been like 2 minutes but I went back to study using this terrible website and got immediately angry so I'm adding more. The fact that people are paying for this is insulting. What I would consider the bare minimum of being a study material, having the answers, isn't there, only having the answers every other question is a joke. I also know it wouldn't be hard to explain how something is the answer, but that doesn't matter when you can do the bare minimum and just let students spend valuable time on other websites to get an explanation. The problems are also hilariously bad for studying, and often are super complex for no reason, seemingly just to waste peoples time, which makes me angrier. As I said earlier, worst online textbook I've ever used, you should be paid to use it, not the other way around.Edit 2:I'm back the next day, angry once again at having to use this terrible textbook. This time I'm specifically angry at how terrible the problems are. Despite me doing a REVIEW, I cannot do most of the problems in the review of stuff I have already learned even with help from other websites. This is exceedingly unhelpful, as I am trying to study for my FINALS, which as I'm writing this, are TOMORROW. I could fail and lose my financial aid, all because this textbook is so wildly terrible for actually studying and learning. Every time that I try to either do the homework or study using this terrible book, I spend far longer than I should, all because it is terrible. There is no reason that the review problems are so needlessly complex compared to anything you would generally be doing in a precalculus class. All of this would be nowhere near as big of an issue if the book just explained stuff with the answers, but I guess that's just too much effort for whoever wrote it to put in. I'm convinced the person who wrote the textbook hates students at this point, they are bad at teaching math and should feel bad for putting students through this. Never use this website if you don't have to.
