here is another solution.....
cos^2x/1+tanx
put tanx = t
sec^2xdx = dt,,,,now substitute,,,,,,
u will get cos^4x/1+t.....now we can write cos^4x = (cos^2x)^2
applying half angle formula of cos2x....we get cos^2x = 1+cos2x/2
now cos2x = 1-tan^2x/1+tan^2x....now substitute,,,,,,,this to question...
further solution is here....
