put cos =t. since it is constant it wont matter. now convert cosx into half the tangents and put tan(x/20)=z..dis is a substitution and dx will change accordingly.

[ ] [ ]dx/(cosx+cos )
=[ ] [ ]sec2(x/2)dx/((1-tan2(x/2)+cos(1+tan2(x/2)))
Now take tan(x/2)=z as told by aniket.
and you will get form of [ ][ ]dt/(c-at2)
which can be solved easily
