【题目】ex2是fx的一个原函数,则xf(x)的导数dx如图2.设$$ e ^ { x ^ { 2 } } $$数是f(x)的一个原函数,则$$ \int _ {
故$$原式 式 = \frac { 1 } { 2 } \int _ { 0 } ^ { \frac { \pi } { 2 } } \cos x d e ^ { 2 x } = \frac { 1 } { 2 } \left[ ( e ^ { 2 x } \cos x ) | _ { 0 } ^ { \frac { \pi } { 2 } } + \int _ { 0 } ^ { \frac {...

यदि int e^(-(x^2)/(2)) dx = f(x) और अवकल समीकरण (dy)/(dx) = 1 + xy का हल y = ke^((x^2)/(2))f(x) + Ce^((x^2)/(2)) है, तब k का मान बराबर है: (ज
(x^p)dx 收敛;但因为当 0p≤1 时积∫_1^(+∞)(arctanx)/(x^p)⋅sinx|dx 发散,所以当 0p≤1 时积分∫_1^(+∞)(sinx)/(x^p)tanxdx 条件收敛()令 t=x^2 ∫_0^(+∞)sin(x^2)dx=∫_0^(+∞)(sint)/(2√t)dt 由∫_0^(+∞)(sint)/(2√t)dtdt条件收敛,可知2积分∫_...
若 f(x_n)0 ,则 f(x)0 ,由(1)式,有 f(x)(ε_0)/2 从而∫_(x_0)^(x_n)f(x)dx(e_0)/2∫_(x_a^(x_4)^e(dx)=(e_08)/2 dx =正常数);若 f(x_n)0 ,则 f(x)0 由(1)式,有 f(x)-(ε_0)/2 从而∫_(s_a+b)f(x)dx-(e_0)/2∫_x_0^(a_0θ)...
