Integral(2/(x^2), (x, 0, 1))
Detail solution
  1. The integral of a constant times a function is the constant times the integral of the function:

    2x2dx=21x2dx\int \frac{2}{x^{2}}\, dx = 2 \int \frac{1}{x^{2}}\, dx

    1. Rewrite the integrand:

      1x2=~0\frac{1}{x^{2}} = \tilde{\infty} 0

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

      ~0dx=~0dx\int \tilde{\infty} 0\, dx = \tilde{\infty} \int 0\, dx

      1. Integrate term-by-term:

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

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

          (1x)dx=1xdx\int \left(- \frac{1}{x}\right)\, dx = - \int \frac{1}{x}\, dx

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

          So, the result is: log(x)- \log{\left(x \right)}

        The result is: 00

      So, the result is: NaN\text{NaN}

    So, the result is: NaN\text{NaN}

  2. Add the constant of integration:

    NaN+constant\text{NaN}+ \mathrm{constant}


The answer is:

NaN+constant\text{NaN}+ \mathrm{constant}
