Descripción

Product description RENUS 2-Line Engineering Scientific Calculator Advanced Scientific Calculator with 2-line display/240 functions/Large screen/Replay function. Ideal for professional and student use in mathematics, science, algebra, trigonometry, statistics, engineering, chemistry and physics. 3 modes, COMP(Basic Arithmetic Calculations), SD(Standard Deviation), REG(Regression Calculations). 240 functions, support Basic Calculation (a b/c /%/degree,min.,sec./FIX.SCI.RND), Memory Calculation(answer /consecutive /independent /variables /formula storage and repetitive operation), Scientific Function Calculation (sin,cos,tan & inverse /cot,sec,csc /hyperbolic & inverse /log and antilogarithms /Log to base /√, x√, 3√, x², x³, x(-1), X!, xπ，A（n/m）, C(n/m)... /angle unit conversion /coordinate conversion /EGN /random number), Statistical Calculation (standard deviation /regression calculation /linear regression). A multi-functional helper for students in middle/high school, can largely raise your efficiency and accuracy. All steps are clearly stated in the user manual. Arithmetic Calculations Negative values inside of calculations must be enclosed within parentheses. It is not necessary to enclose a negative exponent within parentheses. You can skip all [ ) ] operations before [ = ] Degrees,Minutes,Seconds Calculations you can perform sexagesimal calculations using degrees(hours),minutes,and seconds ,and convert between sexagesimal and decimal values. Example: To convert the decimal value 12.58 to a sexagesimal value and then back to a decimal value Fraction calculations Values are displayed in decimal format auto matically whenever the total number of digits of a fractional value (Integer+numberator+denominator+separator marks) exceeds 10 results of calculations that mix fraction and decimal values are always decimal Battery Included AAA Battery x 2 AAA R03 1.5V Super heavy duty Not for retall market WARNING:DO NOT DISPOSE OF IN FIRE Battery may explode or leak and cause personal injury Compatible Battery: 2 * AAA battery (Icluded) Power Consumption: 0.0002W RENUS 2-Line Engineering Scientific Calculator User Manual Included Auto Shut-down: No operation in 5min Item Size：6.1 * 3.3 * 0.6" Item Weight: 0.256lb Package Size: 6.2 * 3.5 * 0.7" Package Weight: 0.29lb View Display: The view display feature allows users to view formula, scores, and symbols as you see in textbook. Various application: Apply to such field as trig functions, logarithms, reciprocals, powers and roots, averaging, summation, equations . Testing helper: Standardized Testing Organization approved use for SAT, PSAT / NMSQT, AP Chemistry, AP Physics and more. Replay Key: Without having to restart the entire process, the special feature of replay allows to go back and change the individual numbers of the equation.
