Move the pieces by touching the screen. You can see that the sum of the areas of small squares is equal to the area of large squares.

Measure the derivative value while moving the tilt measurement tool. You can change the shape of several mathematical functions by touching the screen.

How to calculate the area of a circle If you cut the circles and put them on each other, they gradually become a shape close to the rectangle. At this time, the horizontal length of the rectangle becomes half of…

Sierpinski triangle is a fractal and attractive fixed set with the overall shape of an equilateral triangle. In this simulation, Create a Sierpinski triangle by endlessly drawing circles.

The Pythagoras tree is a plane fractal constructed from squares. Invented by the Dutch mathematics teacher Albert E. Bosman in 1942, it is named after the ancient Greek mathematician Pythagoras.

A Voronoi diagram is a partitioning of a plane into regions based on distance to points in a specific subset of the plane. That set of points is specified beforehand, and for each seed there is a corresponding region consisting…
