What is the value of \(\frac{\tan 60° - \tan 30°}{1 + \tan 60° \tan 30°}\)?
Answer: A
This expression is in the form of the tangent subtraction formula: \(\tan(A - B) = \frac{\tan A - \tan B}{1 + \tan A \tan B}\).
Here, A = 60° and B = 30°.
So, the expression is equal to \(\tan(60° - 30°) = \tan 30°\).
