【實用教育app】Persona Equation 4D|最夯免費app-綠色工廠好玩App

*I confirmed the present versions on sale work with iOS8 and iPhone6/6Plus simply. (9/13)This application is a biquadratic/cubic/quadratic/linear equation and 4/3/2-VLE simultaneous equations calculator. For educational purpose, it equips with fraction/square root shape in input and calculation result display. (Basically, it calculates by the numeric. But up to the cubic equation, I added the process to hold the fraction answer in the level general CAS can do.) Except solving equation, below functions are equipped.・Overview graph of the equation・Coefficient calculation from solutions.・Inequality・Slope/y-coordinate calculation of ordered x-coordinate・Maximal/minimal coordinate of the equation・Linear/quadratic equation that through ordered points( Spec )・Simultaneous equations 4 input sheets/1 answer sheet and linear/quadratic/cubic/biquadratic equation 1 input sheet/1 answer sheet/1 coordinate sheet are equipped.・The touch action direct to the digit you want to change, makes numerical input or modify. It automatically starts calculation of the results.・2 kind Numeric keyboards are equipped. (√/fraction/imaginary number can be entered)・Copy / paste function of a sheet or each numeric.・1 memory・Graph display of linear/quadratic/cubic/biquadratic equation・Rounding location and rounding type is configurable.・Fraction/√ can be entered and displayed.・Whether displaying imaginary number solution or not is configurable.・Configurable decimal point/separator(5 types) and separator position(4 types), and numeric(17 types).・Landscape mode display(After tweet, iPhone/iPod touch: one numeric enlargement/iPad: split screen)・iPhone/iPod touch: 10-digit display / iPad: 14-digit display・Internal calculation operations: 16-digit decimal or fraction or square root (Not binary floating/double)
