Recently, we discussed the proofs of the Pythagorean theorem by using trigonometric ratios and submitted our paper to the international mathematical journal(refereed), Parabola. Fortunately, our paper was accepted into the journal and will appear on the journal website.

One of our members, Kise, is a junior high school student, and one of ours, Uehara, is a high school student. They are good at math and are gifted. They have a deep and sharp insight into anything. I am happy to study with young mathematicians.
