1. Enter values in the two input fields “Re” and “Im” in the upper left corner.Press the button marked with a circle to enter a red circle and enter a value.
2. By moving the red dot representing n at the bottom of the screen,the value and position of the nth root will be displayed.
3. By pressing the“Cartesian Coordinates”and“Polar Coordinates” buttons on the right,the solutions will be displayed in each system.

1. Enter the total population N, the number of initially infected persons I, the number of recovered persons R, the recovery rate γ, and the infection rate β, and press the Run button.
2. You can see the changes in the number of infected (red), uninfected (green), and recovered (blue).The number of infected persons increases rapidly, but after a certain point, it decreases, and the infection eventually subsides.
3. Check how the number of infected persons changes under different conditions.

1. Enter the appropriate number of data in the “Number of data n” input box. Use the keyboard in the upper left corner to enter values.
2. Press the change button in the upper right corner to update the frequency distribution table and histogram at the bottom of the screen.
3. When you move the red dot at the bottom of the screen, which indicates the number of classes (k), the frequency distribution table and histogram will change according to the number of classes.
4. Press the“polyline” button to display the degree line. Press it again to hide it.
5. Press the“Sturges Formula”button to calculate the number of classes from the Sturges formula and display the result.
6. The“back”button displays the histogram of class numbers obtained from the Sturges formula behind the original histogram. The“front”button displays the histogram in front of the original histogram.

1. Enter appropriate values in the two input fields“real part”and“imaginary part”in the upper left corner. Use the keyboard in the lower right corner to enter values.
2. By moving the red dot at the bottom of the screen to the left or right, you can change the value of n in the n-square root. The value of the n-square root is displayed on the left side according to the value of n, and the position of the n-square root is displayed on the complex plane.
3. You can switch the display of n-square root values by using the “Cartesian coordinates display” and “Polar coordinates display” buttons on the right side. The values are displayed in Cartesian or polar coordinates.
