The Joinus Scientific Calculator JS-82MS-5 is a model of scientific calculator designed primarily for students in middle school, high school, and college.It is highly similar in function and appearance to the widely-used Casio FX-82MS series of calculators, a common pattern for many budget-friendly scientific calculator brands.Key Features and SpecificationsFeatureDetail (Based on available manuals and product listings for JS-82MS/JS-82MS-A)ModelJS-82MS-5 (or variants like JS-82MS-A)TypeScientific CalculatorFunctions240 Calculation Functions (Standard for this class of calculator)Display2-Line Display (Input expression on the top line, result on the bottom line). Typically 10+2 digits (10 mantissa digits + 2 exponent digits).Key FunctionsIncludes standard functions for:$\bullet$ Trigonometry ($\sin$, $\cos$, $\tan$, and their inverses)$\bullet$ Logarithms ($\log$, $\ln$, $10^x$, $e^x$)$\bullet$ Powers and Roots ($x^2$, $\sqrt{}$, $x^3$, $\sqrt[3]{}$, $\wedge$)$\bullet$ Fractions (Input, conversion, mixed number operations)$\bullet$ Statistics (SD, REG modes)$\bullet$ Coordinate Conversions (Polar $\leftrightarrow$ Rectangular)$\bullet$ Factorials, Permutations, and Combinations ($x!$, nPr, nCr)Algebraic LogicLikely uses the S-V.P.A.M. (Super Visually Perfect Algebraic Method) or a similar system, allowing expressions to be entered as they are written in a textbook.MemoryMultiple variable memories (typically 9, labeled A, B, C, X, Y, etc.) and an Independent Memory (M).Power SourceTypically uses one or two AAA batteries.CaseComes with a protective sliding hard case.
