进行求导运算的结果是什么? 二、解析 令u = x − t,则: t=x–u. dt=–du. 又由于 t ∈ (0,x), 因此,u = x − t ∈ (x,0). Next 于是: ∫0xtf(x–t)dt= –∫x0(x–u)f(u)du= ∫0x(x–u)f(u)du= ∫0xx⋅f(u)du–∫0xu⋅f(u)du= x∫0xf(u)du–∫0xu...
【解析】令u=x-t,原方程化为: f(dt=z+(u)du-; 。u时(u 两边对x求导,得f(x)=1+f(u)du+f() ①; -rf()=1+f(u)du… 两边再对x求导,得f(x)=f(x); 解得nf(x)|=x+n|C,即f(x)=Ce2; 将x=0代入①,得f(0)=1; f(0)=Ce°=1,解得C=1; ∴f(x)=e2.相...
高等数学 积分函数的奇偶性的一个问题,求指点若f(x)是奇函数,则 $$ \int _ { 0 } ^ { x } $$f(t)dt为偶函数;若f(x)是偶函数,则 $$ \int _ { 0 } ^ { x } $$f(t)dt为奇函数.&偶函数的原函数之一为奇函数“导函数为奇函数,那么原函数为偶函数;导函数为偶函数,那么...
