Question:
In a triangle $ABC$, if $\tan A + \tan B + \tan C = 6$ and $\tan A \tan B + \tan B \tan C + \tan C \tan A = 11$, find the value of $\tan A \cdot \tan B \cdot \tan C$.
Step-by-Step Solution
Key Concept: In any triangle $A + B + C = \pi$, the identity $\tan A + \tan B + \tan C = \tan A \tan B \tan C$ always holds. Apply it directly.
