Sharp EL-500W series include a range of scientific calculators capable of displaying 2 lines, with multi-line playback. It is the successor to the Sharp EL-500V series. ==Features== Starting with the W series, this product line supports dual-line displays with multiple line playback, constant calculation, chain calculation, similar to the Casio FX-MS series, TI-34 II Explorer Plus. The upper line shows entered expression (up to 12 characters at a time). The basic EL-509W, EL-531W models includes 272 functions, which include power/root/logarithm functions, trigonometry functions, factorials, random functions, fractions, angle unit conversion, polar/cartesian coordinate conversion, binary/pental/octal/hexadecimal calculations (includes logical ops), 1-2 variable statistics with 6 regression models (linear, logarithmic, exponential, power, inverse, quadratic). Calculations are done in 14 digits internally. EL-509W uses 2 LR44 batteries EL-531WG uses 2 LR44 batteries and solar cells. EL-531WH runs on 1 AA battery instead of 2 LR44 batteries. EL-520W adds 52 physical constants, 44 unit conversions, complex number calculation, 2-3 variable linear equation solver, quadratic equation/cubic function equation solver, Newton generic equation solver, numeric derivative/integral functions, formula memory (max 4 formulae, 256 characters total), algebraic substitution (simulation calculation) to EL-509/531W, for total of 419 functions. It is powered by 2 LR44 batteries or light. EL-506W adds matrix calculation, list calculation (max 4 lists, 16 elements/list) to EL-520W, for total of 469 functions. EL-500M is a single line version of EL-509W, which contains only the dot matrix line. Dot matrix line only shows 11 characters. Memory register is reduced from 9 to 1. Removed functions include engineering unit display mode, cubic root/power, hyperbolic trigonometry, random dice, random coin, random integer, angle unit conversion, polar/cartesian coordinate conversion, multi-line playback, binary/pental/octal/hexadecimal calculations, 2-variable statistics, 2-key roll-over. However, it adds reduction study, highest common factor/lowest common multiple, quotient/remainder calculation. Total function is 131. The keyboard is not plastic like the others in the lineup. EL-501W does not support DAL (Direct Algebraic Logic), and only has the 7-segment digit line in EL-509W. It only supports 8-digit mantissa display in scientic notation mode. Functions are further stripped down from EL-500W. Removed functions include last answer recall, nPr/nCr, reduction study, highest common factor/lowest common multiple, quotient/remainder calculation, equation playback. However, it gains cubic power/root, hyperbolic trigonometry, angle unit conversion, polar/cartesian coordinate conversion, complex number calculation, Bin/Oct/Hex calculations (without logical ops) over EL-500W. Total function is 131. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Sharp EL-500W series」の詳細全文を読む スポンサード リンク
