(15*sqrt( - a**2*x**2 + 1)*asin(a*x)*a**3*x**3 + 15*sqrt( - a**2*x**2 + 1) *asin(a*x)*a**2*x**2 - 15*sqrt( - a**2*x**2 + 1)*asin(a*x)*a*x - 15*sqrt( - a**2*x**2 + 1)*asin(a*x) + 33*sqrt( - a**2*x**2 + 1)*a**3*x**3 + 33*sqrt ( - a**2*x**2 + 1)*a**2*x**2 - 33*sqrt( - a**2*x**2 + 1)*a*x - 33*sqrt( - a**2*x**2 + 1) - 15*a**5*x**5 - 38*a**4*x**4 + 52*a**3*x**3 + 87*a**2*x**2 - 33*a*x - 48)/(15*sqrt( - a**2*x**2 + 1)*a*c**3*(a**3*x**3 + a**2*x**2 - a*x - 1))
