Homework Statement
[itex]\dfrac{tan\left( \theta + 2\pi /3 \right) - tan\left( \theta + \pi /6 \right) + cos\left( \theta + \pi /6 \right)}{\sqrt{3}} \\
\theta \in \left( -5 \pi /12, - \pi /3 \right)
[/itex]
The Attempt at a Solution
At maximum, f'(x)=0
sin(θ+∏/6)=0
But there is no theta in the given interval that satisfies this equation.
