Let s(x) be continuous for all x and anti-periodic mod L : s(x+L) = -s(x). Let f(x) be continuous on [0,1]. Prove that the integral of f(x)*s(lambda*x) over [0,1] tends to zero as lambda approaches infinity. hint: break up integral into some appropriate chunks。
这门课是傅立叶的,但是我死活没在课本上找到相关内容,求数学(这门课与工程有关)大神解答!国内学数学的也行,google翻一下就行···求救。
会的分数全给你了!!!!!!!!!!!cang老师种子也给你了
