 note = {application/pdf, In this paper, we are concerned with a discretization of the trigonometric functions. Noting the fact that the sine and cosine functions are obtained as the fundamental solution of the ordinary differential equation for simple harmonic oscillation, we discretize these functions by means of a difference equation associated with that equation. We report that the discrete functions which we obtain have many fruitful properties., 本稿では正弦関数と余弦関数の離散化について考える. これらの関数は単振動に対する微分方程式の素解として得られるという事実に注目し, 対応する差分方程式を用いた離散化を行う. これにより, 興味深い性質を持つ離散系関数が構成されることを報告する., Article, 富山大学人間発達科学部紀要, 4巻2号, Page 203-216},
