My Students LOVE this!!! Perfect for ALL calculus students, AB, BC, Honors and College!! This new Flip Book includes all 24 derivative formulas that students must learn to succeed in Calculus, plus some hints and examples. Two versions of the flip book are included, one with the formulas typed in and the other for the students to fill in themselves. The Flip Book is a perfect size- and oh so easy to put together - paper saver, too.
