Integrate

Symbolic integration.

Qurak evaluates indefinite and definite integrals symbolically. For integrals that don't have a closed form, use `NIntegrate` for a numeric answer instead of waiting for `Integrate` to give up.

可独立核查：此函数的答案会通过另一条途径重新推导并比较——工作台和 verify 工具会自动完成，因此错误答案会被发现而不是被采信。历史 →

形式

Integrate[f, x]

Integrate[f, {x, xmin, xmax}]

Integrate[f, {x, xmin, xmax}, {y, ymin, ymax}, …]

Integrate[f, {x, y, …}∈ reg]

验证过的示例Integrate[x, x] → x^2/2 Integrate[x^2, {x, 0, 1}] → 1/3 Integrate[Sin[x], {x, 0, Pi}] → 2 Integrate[Log[Sin[x]], {x, 0, Pi/2}] → -1/2*(Pi*Log[2])Integrate[Log[x], x] → x*(-1 + Log[x])ToString[Integrate[x Log[x], x], InputForm] → (x^2*(-1 + 2*Log[x]))/4 ToString[Integrate[Log[2 x], x], InputForm] → -x + x*Log[2*x]ToString[Integrate[E^(-x), x], InputForm] → -E^(-x)选项
