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.

Independently checkable: an answer for this function is re-derived by a different route and compared - the workbench and the verify tool do this automatically, so a wrong answer is caught rather than trusted. History →

Verified examplesIntegrate[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)Options
