this can be resolved by covering cosx into half angle tan formula ......when u will do that... numerator will become some function of sec^2(x/2)..and denominator. will contain tan(x/2)....then put
tan(x/2)=t
sec^2(x/2)*(1/2)dx=dt....and it will be further solved..... try this.. if worked then OK... otherwise u can delete this ans.... so that someone else can answer it.....
