About Persona Equation 4D
This application is a biquadratic/cubic/quadratic/linear equation and 4/3/2-VLE simultaneous equations calculator.
Repeating a similar calculation is sometimes necessary. Full number input again and again is a nuisance. Don't you think it's better if the calculation result comes only by different point correction? This application fulfills it.
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
Not all calculation finishes with getting the result. You often have the demand such as follows.
・To get results when the input is different. And the results of more various inputs.
・To get the input of the adjusted result.
This application watches a touch action to display number itself and does numerical value correction or input.
It makes simpler and easier the operation (correction, recomputation) like above cases.
( 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(18 or 19(iOS8)).
・Landscape mode display(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(Not binary floating/double) or fraction or square root. (For error minimising)
・Multitask (for i-Pad) and Handoff (2 units or more) of iOS are available.
