## Circumference of a Circle

Find a way to approximate the circumference of a circle. What is the circumference of a circle with a radius of ‘1’?

## Pythagorean Theorem

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.

## Differentiation 2

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

## Area of Circle

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…
