Note for OP
+solved @user1 @user2... to close the thread when your doubt is solved. Mention the users who helped you solve the doubt. This will be added to their stats.what sub are you thinking of making?
In these types mostly im thinking of making it into tan and sec, and also i think of if there are any derivative
sure since there is cos2x in the numerator, most likely it is a tan/cot subsitution
Also integral of 1/rt something = rt something
which is what you have here
convert cos 2 x into cos2
cos^2*
and then substitute :)
