MHB Michael Sullivan Precalculus Textbook Arrived Today

Click For Summary
The discussion centers around the transition from David Cohen's precalculus textbook to Michael Sullivan's Precalculus 5th Edition. The original poster finds Cohen's book overly complex, particularly due to its focus on the unit circle, which may be better suited for honors courses. In contrast, Sullivan's textbook is viewed as more accessible for a general student audience, despite its own challenges. The poster has a long history with Sullivan's book, having used it since 2006, and notes its widespread adoption in high school and military online math courses. There is a request for a link to a free online version of Sullivan's textbook, highlighting its perceived ease of understanding compared to Cohen's work.

I finally got my Michael Sullivan Precalculus 5th Edition textbook today. I have decided to part ways with my David Cohen book. It makes no sense to keep it. It is truly over my head.

By this I don't mean that Sullivan's book is a walk in the park. It can be intense depending on the topic and/or chapter. Cohen's book concentrates more on the unit circle as a guide through most of the problems. It is probably meant for an honors precalculus course.

So, parting ways after so many years. I had the 5th edition Sullivan precalculus textbook back in 2006. Soroban helped a lot back in 2006. Sullivan's book is directed more for a general student population as opposed to a group of talented or advanced math students.

Can I please have the link to the free online Sullivan textbook? Sullivan is so much easier to read than David Cohen. Do you have the 5th edition of the precalculus book?
 

Thread 'What did you do with your old college textbooks?'

Many years ago, as the internet was coming of age, I burned over 500 pounds of technical manuals. I realized I can look things up on the internet faster than I can find something in a technical manual. And just about anything I might need could be found online. But letting go of my several shelves worth of college text and other science books is another matter. I can't bring myself to get rid of them but there is very little if anything I can't find online now. Books are heavy and a pain...
