摘要
针对傅里叶系数计算中积分运算复杂、计算量大的困难,提出了三种计算技巧。不仅能减少计算量,还能使学生摆脱单一的套公式计算的枯燥感,将数学知识融会贯通,提高学习兴趣。
It is difficult to calculate Fourier coefficients because of so many integrations. This paper pro- vides three calculating skills to reduce computational work. On the other hand, these skills can improvestudents' interest in learning mathematics.
