$\begin{aligned} \large \log\left(\sin 30\right) + \log\left(\cos 30\right) + \log\left(\tan 30\right) + \log\left(\csc 30\right) + \log\left(\sec 30\right) + \log\left(\cot 30\right) & = \log\left(\sin 30 × \cos 30 × \tan 30 × \csc 30 × \sec 30 × \cot 30\right)\\ & = \log\left(1\right)\\ & = \color{#69047E}{\boxed{0}} \end{aligned}$
