\int \frac{d x}{7+5 \cos x} is equal to

Correct Answer is : 1√6tan−1(1√6tanx2)+c

{1}/{\sqrt{3}} \tan ^{-1} ( {1}/{\sqrt{3}} \tan \frac{x}{2}) +c

{1}/{\sqrt{6}} \tan ^{-1} ( {1}/{\sqrt{6}} \tan \frac{x}{2}) +c

\frac{1}{7} \tan ^{-1} (\tan \frac{x}{2}) +c

\frac{1}{4} \tan ^{-1} (\tan \frac{x}{2}) +c
