One of the most requested features for "Hands-On Precalculus" was the ability to pause, rewind, and seek the videos. We heard you! Just like in the newer "Hands-On Calculus," our precalculus book now allows you to quickly jump to any point in any of the videos. In addition to these improvements, you can now also log in to our books to keep track of your progress.
The updated version of "Hands-On Precalculus," with the new calculator and a cleaner look for the text, will be available later this week.
