$$\int\limits_{0}^{1} \frac{3}{\sqrt{1 - x^{2}}}\, dx$$
Integral(3/(sqrt(1 - 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:

      TrigSubstitutionRule(theta=_theta, func=sin(_theta), rewritten=1, substep=ConstantRule(constant=1, context=1, symbol=_theta), restriction=(x > -1) & (x < 1), context=1/(sqrt(1 - x**2)), symbol=x)

    So, the result is:

  2. Now simplify:

  3. Add the constant of integration:
