Calculation of Pi 與 The Matrix Mentor 使用情況與統計

Using the area of the square and the area of the inscribed circle, the method of finding π in the Monte Carlo simulation, the method of using the Length of side of regular polygon inscribed and circumscribed in the circle, the method of Buffon's needle (also Monte Carlo simulation), each is displayed by this application. The data to be displayed is calculated sequentially by the CPU, and in the method using the regular polygon, we calculate it by using the Pythagorean theorem repeatedly. Each calculation method is on the internet. It is interesting that the numerical value converges to π. If you use it when teaching π in school, it will enhance students' interests of interest.

The Matrix Mentor

Are matrices getting you down? Don’t worry… THE MATRIX MENTOR IS HERE TO HELP The Matrix Mentor provides a visual understanding of linear transformations. Where others may teach you the mathematical rules that can be hard to remember, our playground provides a visual and interactive demonstration of the inner workings. SCARED OF MATRICES? DON'T BE! At its core, The Matrix Mentor is a visual learning tool, designed to bring matrices from an abstract mathematical concept to a concrete application. Whether you think about vectors as 3D points or a RGB color value, the fundamentals hold true. - Experiment with different types of transformations - Discover how matrices interact with a given vector, or a whole grid of points - Develop your intuitive sense for reading matrices and linear transformations Do yourself a favour, and start playing with The Matrix Mentor today!
