Integral(cot(x), (x, 0, 1))
Detail solution
  1. Rewrite the integrand:

    cot(x)=cos(x)sin(x)\cot{\left(x \right)} = \frac{\cos{\left(x \right)}}{\sin{\left(x \right)}}

  2. Let u=sin(x)u = \sin{\left(x \right)}.

    Then let du=cos(x)dxdu = \cos{\left(x \right)} 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(sin(x))\log{\left(\sin{\left(x \right)} \right)}

  3. Add the constant of integration:

    log(sin(x))+constant\log{\left(\sin{\left(x \right)} \right)}+ \mathrm{constant}


The answer is:

log(sin(x))+constant\log{\left(\sin{\left(x \right)} \right)}+ \mathrm{constant}
