$\lim_{\theta \to 0} \frac{\sin7\theta}{\theta + \tan7\theta}$
What do you do with the theta in the denominator, the one that isn't with tan? If it weren't in there, $\tan\theta$ would just be $\frac{\sin\theta}{\cos\theta}$, but with the other angle in the denominator. What do you do? How does that other values presence change the question?
