( - 2*sqrt(tan(c + d*x))*sqrt( - 2*tan(c + d*x) - 3) + 4*int((sqrt(tan(c + d*x))*sqrt( - 2*tan(c + d*x) - 3)*tan(c + d*x)**2)/(2*tan(c + d*x) + 3),x )*d + 3*int((sqrt(tan(c + d*x))*sqrt( - 2*tan(c + d*x) - 3)*tan(c + d*x))/ (2*tan(c + d*x) + 3),x)*d + 3*int((sqrt(tan(c + d*x))*sqrt( - 2*tan(c + d* x) - 3))/(2*tan(c + d*x)**2 + 3*tan(c + d*x)),x)*d)/(4*d)
