{ "item_title" : "The Texas Instruments Ti-92 Plus Graphing Calculator a", "item_author" : [" Richard Murdoch Montgomery "], "item_description" : "This book contains a complete progressive guide to the Texas Instruments TI-92 Plus Graphing Calculator: its physical operation, operating system, exact and approximate arithmetic, algebraic language, computer algebra system, graphing environments, calculus, matrices, vectors, statistics, probability, geometry, programming, scientific and engineering applications, finance, discrete mathematics, long-term preservation, pedagogy, examination ethics, capstone projects, reference appendices, a conclusion, and an index of words and commands.It is written for the student who wants fewer miracles and better methods; for the teacher who wishes to turn a machine into an occasion for judgement; for the engineer who knows that a convenient answer can still be a wrong one; for the collector who values old instruments because they remain intellectually alive; and for the mathematically curious companion who suspects, correctly, that a symbolic calculator is less a servant than a rather literal colleague.The TI-92 Plus is not merely a calculator. It is a compact symbolic mathematics workstation: mathematics workstation, a programming environment, a data-analysis device, a geometry laboratory, and a small archive of late twentieth-century mathematical optimism. To use it well is not merely to know which key follows which, but to understand why a command works, what assumptions it smuggles in, and how its result may be verified.Every equation in this volume is intended to be introduced rather than dropped upon the page as if mathematics were weather. Variables are defined, command sequences are boxed, examples are worked, and exercises are resolved. The prose attempts to keep calculation and judgement in civil conversation; whenever the two disagree, judgement is invited to preside.I would be very glad if corrections, misprints, computational errors, ambiguities, or omissions are transmitted to [email protected]. Any remaining errors are exclusively my own fault. The machine may calculate quickly, but authors are slower devices, and occasionally less well calibrated.This edition is formatted as a no-bleed KDP-oriented interior, using safe margins and a larger technical trim so that diagrams, command boxes, tables, and equations may breathe without trespassing upon the binding.", "item_img_path" : "https://covers4.booksamillion.com/covers/bam/9/79/818/898/9798188980979_b.jpg", "price_data" : { "retail_price" : "39.99", "online_price" : "39.99", "our_price" : "39.99", "club_price" : "39.99", "savings_pct" : "0", "savings_amt" : "0.00", "club_savings_pct" : "0", "club_savings_amt" : "0.00", "discount_pct" : "10", "store_price" : "" } }
