For starters, the answer is meant to be negative since 23pi/12 lies in the 4th quadrant.
Note that:
1. $\displaystyle \tan \frac{23 \pi}{12} = - \tan \frac{\pi}{12}$ by symmetry of the unit circle.
2. $\displaystyle \frac{\pi}{12} = \frac{\pi}{3} - \frac{\pi}{4}$ so using the compound angle formula is suggested ....
