$$\int\limits_{0}^{1} x^{3} \sqrt{x^{2} + 1}\, dx$$
Integral(x^3*sqrt(1 + x^2), (x, 0, 1))
Detail solution
  1. Rewrite the integrand:

    SqrtQuadraticDenomRule(a=1, b=0, c=1, coeffs=[1, 0, 1, 0, 0, 0], context=(x**5 + x**3)/sqrt(x**2 + 1), symbol=x)

  2. Now simplify:

  3. Add the constant of integration:
