$$\int\limits_{0}^{1} \tan{\left(x \right)}\, dx$$
Integral(tan(x), (x, 0, 1))
Detail solution
  1. Rewrite the integrand:

  2. Let .

    Then let and substitute :

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

      1. The integral of is .

      So, the result is:

    Now substitute back in:

  3. Add the constant of integration:


The answer is:
