物理背景在Fourier级数教学中的重要性

摘要

This paper reveals the significance of expressing a periodic function by Fourier series in physical aspects and illustrates, from the close relationship between mathematics and physics, that physical background is very important in teaching Fourier series.%从物理方面揭示了把一个周期函数表示成Fourier级数的意义，并且从数学与物理的密切关系等方面说明物理背景在Fourier级数教学中的重要性。
