Best ResponseYou've already chosen the best response.1sweet so that means that: \[\tan ({5\pi \over 12} )= \tan ({3\pi \over 12} + {2\pi \over 12}) = \tan ({\pi \over 4} + {\pi \over 6})\]

Best ResponseYou've already chosen the best response.1Yep! make sure you use (1/4)* pi\[\tan ({\pi \over 4} + {\pi \over 6})\]
