Integral(1/(x - 1*2), (x, 0, 1))
Detail solution
  1. Let u=x2u = x - 2.

    Then let du=dxdu = dx and substitute dudu:

    1udu\int \frac{1}{u}\, du

    1. The integral of 1u\frac{1}{u} is log(u)\log{\left(u \right)}.

    Now substitute uu back in:

    log(x2)\log{\left(x - 2 \right)}

  2. Now simplify:

    log(x2)\log{\left(x - 2 \right)}

  3. Add the constant of integration:

    log(x2)+constant\log{\left(x - 2 \right)}+ \mathrm{constant}


The answer is:

log(x2)+constant\log{\left(x - 2 \right)}+ \mathrm{constant}
