Integral(E^(-x^2)/x, (x, 0, 1))
Detail solution
  1. Let .

    Then let and substitute :

    1. The integral of a constant times a function is the constant times the integral of the function:

        EiRule(a=1, b=0, context=exp(_u)/_u, symbol=_u)

      So, the result is:

    Now substitute back in:

  2. Add the constant of integration:


The answer is:
