General expression of this definite integral ?

Dear all, 
I am looking for the general expressions of the following definite
integrals 
          Int [ x^n * sqrt[(c + x)/(c - x)]] 
and     Int [ x^n * sqrt[(c - x)/(c + x)]] 
with the integration range from a to b,
where a, b, c = constants 
n = n-th degree power

I try in several mathematical packages but only specific solutions are
computed by putting n= 0,1,2... seperately in the above expression.
Besides that, no information available from many famous integral
handbooks, e.g. W. Grobner and N. Hofreiter, Integraltafel, Zweiter Teil,
Bestimmte Integrale (Springer, Wien, 1958).

Could anyone suggests how tackle this problems ?

Looking forward your helping hands as soon as possible! Thanks! 
Cheers,
Jeffrey M.L.Tan
