Persona Equation 4D

This application is an Equation solver. (Linear/quadratic/cubic/quartic equation and inequality. Simultaneous equations until 4x4) For both educational purpose and practical purpose like engineering, it equips the below functions that were not available in existing similar software. * Calculation parameters expansion like slope,maximum,minimum,etc.. * Expansion of calculation direction to find equation coefficient from solution. * Equipping input and calculation result with fractions, number with square root.

It equips User Interface suitable for Touchscreen. (Direct touch to displayed number works as number input or modification, or switching between result and input.) If you have been calculating equation using Surface Pro,2in1 PC, etc., it will reduce working time. Please try this application. (It can be controlled from Mouse, TouchPad. But direct feeling fades a little.)
