Lost the manual for your TI-89 Titanium calculator? Or just want a spare reference? This is the official guidebook / instruction manual published by Texas Instruments. Please be super clear: this listing is for the BOOK ONLY. The actual TI-89 Titanium graphing calculator is NOT included. It's the full guide that shows you how to use all the functions, solve equations, graph, program, and more. If you're struggling to figure out how to use your fancy calculator for class, this book is a lifesaver. It's the same one that (ideally) came in the box. Make sure you're buying this because you need the instructions, not the calculator itself! Perfect for students, engineers, or anyone who wants to get the most out of their device.
