   I have checked: terms remain integrable if algebraic prefactors are   
   taken apart. Your 94 additive terms should work as elementary exercise   
   material for Mathematica and Rubi.   
      
   As stated in the original thread, I did the integrals from p=0 to p=pi   
   using the substitution   
      
     t = EXP(#i*p) = COS(p) + #i*SIN(p) = c + SQRT(c^2 - 1)   
      
   on Derive 6.10.
