The Easy Way to Calculate Root of Polynomial Equation with Predicted Calc

-
Predicted Calc is a calculator that made by android base, and use genetic algorithm to get unknown value of variables that typed on the equation.  Therefore, this app can also be use for finding root of polynomial equation, like an examples below:
For example to find root of equation:
x2-2*x-3=0
The steps is:
  1. Copy and write the equation without x and y, and with math sign operation, for example by using xo, so the equation can be writed as xo*xo-2*xo-3=0, because  x and y was used by Predicted Calc as input variables.
  2. Press calculate botton to predict one of roots.
  3. Wait until Predicted Calc, approach the best value can be reach.
  4. Because using prediction method, Predicted Calc give error result, this error show how far the prediction give best value that can be reach by your device on that calculation, another calculation could be give the different result as same as or more better error value.
  5. Predicted Calc will give the result -1 and 3 with error=0, like screenshot below:

For prediction every root value, the calculation need to one more time the calculation, because every prediction (single press button calculation) just give one root prediction value.
This’s another approximation finding root with Predicted Calc:
To find root of:
3xo2+2xo-5=0
The writeable equation is:
3*xo*xo+2*xo-5=0

Predicted Calc can also do calculation with different form like below:
xo2-6xo=-5
The writeable equation is:
xo*xo-6*xo=-5

It's Also:
(2x-7)(x-9)=6
The writeable equation is:
(2*xo-7)*(xo-9)=6
And it’s easy

Not just polynomial with orde 2, but Predicted Calc can also calculate on higher orde of polynomial like as:
x3-2x2-9x+18=0
The writeable equation is:
xo*xo*xo-2*xo*xo-9*xo+18=0
C:\Users\Ubay\Documents\Bluetooth Folder\Screenshot_2015-07-20-14-52-31.png  C:\Users\Ubay\Documents\Bluetooth Folder\Screenshot_2015-07-20-14-45-57.png  C:\Users\Ubay\Documents\Bluetooth Folder\Screenshot_2015-07-20-14-45-44.png
Every prediction just give one result, so for get another root value, need more pressing calculation session.

Computational Lab. of Departement of Physics, University of Brawijaya, Malang. initiated to made the simulator of basic beasuring tools that purposed to be used by student or anyone that will be do the laboratory experiment,. The simulator is about Caliper, Micrometer and Osciloscope. This simulator you can find free at Google Play Store with the link below:  Caliper Simulator Micrometer Simulator Osciloscope Simulator or for not advertisement and pro version you can find at Basic Measure App This applications was been made caused by reason as many of new student that do experimental laboratory need more time to learn to use Caliper, Micrometer, or Osciloscope for the first time. With this app, the student could be learn by himself before they do the real experiment. So student will be ready and do the experiment that accorded with the theme of experiment, and not distrubing by the way how to use the measurement tool. Here the preview Video of Basic measurement

Date Calculator

One more, Computational Lab., Dept. of Physics, UB release new android app today, 1 Juli 2015. This app called as Date Calculator and have functionality as general calculator, but with different method where the calculation is based on date data. It's that mean all math operation on this app is basically to optimize user to do math calculation accordingly date math operation. And so in this calculator we will not find minus value, because in Julian Date the minimum value is zero.   Figure 1. The main idea of Date Calculator is because mostly of us do math calculation based on date data. especially for give dateline to some project, with just type number of day that given, we need to make sure what the date is it happen. However the math operation is the basic operation like addition, subtraction , multiplication and division, but if we directly calculate manually, sometimes could be little difficult and we have to see calender to validate.  For example, like in scree
