摘　　要：在求函数的Fourier级数时, 经常遇到将函数在区间 [0, α] 上展成Fourier级数、正弦级数或余弦级数 在教学中恰当地举例及讲解, 学生不但能正确理解这类题目的含义,In process of finding the Fourier-series expansion of the function, usually get some different result,for example the sine-series and the cosine-series. To choice proper examples and explain them exactly in teaching,it will play important role on the students comprehend the meaning of this type of topic and the not uniqueness of Fourier series of the function.

关 键 词：FOURIER级数 正弦级数 余弦级数
