Answer:

        log\left | x+cos\, x \right |+C

Hint:

        \frac{\mathrm{d} }{\mathrm{d} x}(x+cos\, x)=1-sin\, x

Given:

        \int \! \frac{1-sin\, x}{x+cos\, x}dx

Explanation:

Let

        x+cos\; x=t

        (1-sin\, x)dx=dt

        \int \! \frac{dt}{t}=log\left | t \right |+C

                  =log\left | x+cos\, x \right |+C
