Is there a way to solve this integral?



Hi,
is there way, to help maxima along solving the following integral?

integrate(acos((2*c+k*u)/sqrt((1-k^2/4)*(1-u^2))),u);

wolframalpha solves the problem with the input

Integrate[ArcCos[(2*c + k*u)/ Sqrt[(1-k^2/4)*(1-u^2)]],u]

However, I would very much like to be able to stay within maxima.

Regards,
