Let \( f(x) = \frac{4 \sin x}{2 \sin x + 6 \cos x} \).

Then \( f'(x) = \) [Blank space for derivative]

The equation of the tangent line to \( y = f(x) \) at \( a = \frac{\pi}{4} \) can be written in the form \( y = mx + b \) where

\[
m = \frac{2}{3} \quad \text{(incorrect)}
\]

and

\[
b = \frac{2}{1+\sqrt{3}} \quad \text{(incorrect)}
\]

Note: The crosses next to \( m \) and \( b \) indicate that the values provided are incorrect.
