CASIO fx-991CW full tutorial: statistics. matrices. equations. complex numbers. Base-N

Learn every function of the CASIO fx-991CW scientific calculator (and the ClassWiz series fx-570CW) in one video. Each keystroke is shown twice: on the slide and on the real calculator, whose screen shows exactly what yours will show, so you can follow along with your own calculator. The examples come from school and science: chemistry, physics, electronics and technology. Each section ends with a TRY IT YOURSELF question, and each answer is calculator checked. 📚 Buy CASIO fx-991CW from affiliate stores 🔥 Amazon US: https://link.amazon/B0ev6BvYV Amazon Canada: https://link.amazon/B01bsgs8r Amazon UK: https://link.amazon/B0h6h7Ec7 Amazon France: https://link.amazon/B00qo3YtO Amazon Spain: https://link.amazon/B09t9E0Mj Amazon Italy: https://link.amazon/B0hUuLgbJ AliExpress: https://s.click.aliexpress.com/e/_c2QRDgOj eBay: https://ebay.us/VbdA5c WHAT YOU'LL LEARN • Getting to know you: on/off, SHIFT, the HOME screen and apps, the menu keys, SETTINGS, typing and editing, a decimal answer instead of a fraction • Arithmetic, the remainder of a division, fractions, powers and roots, history and replay, Ans and the variables, percentages (VAT and discount) • The FORMAT key, prime factors, technical notation, degrees-minutes-seconds, polar and rectangular coordinates • Derivatives, integrals, sums, logarithms, factorial, permutations and combinations, random numbers, trigonometry, unit conversions, constants of nature • f(x) and value tables, QR codes, statistics and regression, normal, binomial and Poisson distributions, the spreadsheet • Systems of equations, al-Khwarizmi's formula (the abc formula), polynomial equations, the Solver, inequalities • Complex numbers, Base-N (binary, octal, hexadecimal, logical operations), matrices, vectors, ratio, Math Box, errors and the battery 📘 User manual in Dutch and the examples of this explanation: https://www.equaser.com/nl/casio-fx-991cw/ CHAPTERS 00:00 Introduction 00:45 Part 1: Getting started 01:17 Switching on and off 01:40 SHIFT and the gold labels 02:35 The HOME screen and the apps 03:56 Menus: OK, EXE, BACK, CATALOG, TOOLS 05:44 SETTINGS: angle unit, number format, contrast 08:18 Typing and editing 10:34 A decimal answer instead of a fraction 11:54 Part 2: Basic calculations 12:14 Arithmetic 13:08 The remainder of a division (modulo) 14:22 Fractions and mixed fractions 15:28 Powers and roots 17:34 History and replay 18:28 Ans and the variables 20:01 Percent: VAT and discount 23:05 Part 3: Result formats and coordinates 23:33 The FORMAT test 24:51 Prime factors 25:56 Technical notation 27:21 Degrees, minutes and seconds 28:45 Polar and rectangular coordinates: Pol, Rec 32:49 Part 4: Advanced functions 33:52 Derivatives 35:44 Integrals 36:36 Sums with Σ 37:26 Logarithms: pH and carbon-14 40:16 Factorial, permutations, combinations 42:26 Random numbers: dice and coins 45:12 Angular units and trigonometry 48:32 Technical symbols 49:41 Unit conversions 50:54 Constants of nature 53:04 Part 5: f(x), tables and QR codes 53:29 f(x) and g(x) 55:26 The value table 57:34 [3] QR codes 58:20 Part 6: Statistics 58:42 Statistics: mean, standard deviation, quartiles 1:01:51 The regression line: Hooke's law 1:04:53 Quadratic regression 1:07:57 Part 7: Distribution and Spreadsheet 1:08:24 Normal, Binomial and Poisson Distributions 1:13:36 The Spreadsheet: Fill Formula, Sum, Absolute References 1:18:36 Part 8: Equations and Inequalities 1:19:02 Systems of Equations 1:21:31 Al-Khwarizmi's Formula (ABC Formula) 1:23:17 Polynomial Equations: Degree 2, 3 and 4 1:27:04 Solver 1:28:50 Inequalities 1:30:00 Part 9: Complex and Base-N 1:30:27 Complex Numbers 1:36:15 Base-N: Binary, Hexadecimal, Octal, Logic 1:43:55 Part 10: Matrix and Vector 1:44:21 Matrices: determinant, inverse, transpose 1:51:41 Solving a circuit with matrices 1:54:38 [3] Vectors 2:00:47 Part 11: Ratio, Math Box, errors, battery 2:01:13 Ratio 2:02:54 Math Box: dice and coins 2:04:29 Errors 2:06:02 Replacing the battery 2:08:01 Thanks for watching Subtitles: Dutch.
