I f \underset{0}{\int^{π}} \frac{\cos x}{{(x + 2)}^{2}} d x = T

t h e n \underset{0}{\int^{π}} \frac{\sin 2 x}{x + 1} d x = ?

\int \frac{\cos x}{{(x + 2)}^{2}} d x = \sin 2 Ci (x + 2) - \cos 2 Si (x + 2) - \frac{\cos x}{x + 2} + C_{1}

\int \frac{\sin 2 x}{x + 1} d x = \cos 2 Si (2 x + 2) - \sin 2 Ci (2 x + 2) + C_{2}

I {don}^{'} t see any connection, blame it on me \dots

But are you sure {there}^{'} s no typo in your question ?
