Tan Plus One Ac3479

1. The problem is to simplify or understand the expression $\tan a + 1$. 2. Recall that $\tan a$ is the tangent of angle $a$, defined as $\tan a = \frac{\sin a}{\cos a}$. 3. The expression $\tan a + 1$ cannot be simplified further without additional context or values for $a$. 4. If you want to write it as a single fraction, use the common denominator $\cos a$: $$\tan a + 1 = \frac{\sin a}{\cos a} + \frac{\cos a}{\cos a} = \frac{\sin a + \cos a}{\cos a}$$ 5. This is the simplified form as a single fraction. 6. Without more information, this is the final answer.
