Precalculus

The 4 volume calculus books (precalculus/calculus I/Calculus II and calculus III) are the most comprehensive books that is written on calculus. The explanations are very vivid and there are plenty of example exercises in these books I could not wait till get them and Now I have read some chapters from each volume. It is so comprehensive that going to take time to finish these series. These books certainly can be used as the textbook and reference. It has special place on my library. I think any mathematics enthusiast should have all 4 volumes. By the way the priced is excellent for the comprehensive books you receive. Its almost one fourth of price of some of those textbooks that are used in universities.

i despise math but at least this made it easier to understand

Outstanding book. I know it is free online and I worked with it online. Finally purchased the book in softcover. Tremendous reference. I really like the examples and questions that show you how to use knowledge. I supplement thi with online classes and tutorials but when I get stuck this is how I figure out how to move on. I am sure not all this information is needed in precalc but I am glad I will have the text for future reference as well. I am an adult learner getting ready for college level calc

Note: I opted to buy the paperback version. I bought my own copy so I can write in my own notes for class, I bought the paperback and it’s super huge and heavy! The book is ~two inches thick because of it’s ~1,000 pages. It’s definitely something you should keep at home to study with. It’s not really a downside but more of a grim reminder that I have to do so much math to meet my program requirements. Aside from the shocking size and weight, it is a good textbook. The pages are perfect to write on. You can faintly see the color on the other side when written on but it’s nothing that really bothers me, personally. Pages are bound quite well, corners only a little smushed from delivery but it was a used version. TLDR: Overall decent quality but really big and heavy.

I've taught precalculus, and writen an online textbook of my own, so when this was a free Kindle book of the day I grabbed it out of curiosity to see what they did with the subject. Trying to put myself in the student's place, I think this would be good for students, both for self study (if anyone does that any more) and for review or as a supplement to a regular textbook. I haven't noticed any significant omissions. The writing style is clear and straightforward -- I know from writing my own textbooks how hard that is to do. They have many, many step-by-step procedures, and often a short section of frequently asked questions after introducing a topic. There are tons of worked examples, in addition to practice problems and sample tests. Editing is generally good -- not perfect, but I'd give it an A minus. One change I'd make is to link from practice problems to the answers, and ditto for the practice tests. Some sort of split screen, if that's possible on the Kindle, would be ideal. But that's a minor point

Helped me pass my pre cal class. Nice!

I bought the hardcopy of this OER PreCalculus textbook for use with my dual-enrollment college PreCalculus class at a local high school. My students will use the free online version on their iPads, and they are also able to download an app to their smart phones. This textbook is as good as or better than the two and three hundred dollar big name books.

I cannot speak to the quality of the text as it is illegible on my 8" tablet. The publisher compounded this problem by disabling font resizing.

Good book

数学に関することなので英語もわかりやすく、日本の本とはかなり違って内容は非常にわかりやすく、結構すらすらと読めます。英語の勉強にも役立つと思います。

It is an excellent book that covers a lot of area in mathematics that support calculus courses.

Buen libro

Conteúdo perfeito e tudo bem explicado. Recomendo!
