Best ResponseYou've already chosen the best response.12*60 is 120 so cos(120) = \[\frac{ 1 }{ 2 }\] and sin(120) = \[\frac{ \sqrt{3} }{ 2 }\] tan is opp/adj which will then give you an exact answer of \[\sqrt{3}\]

Best ResponseYou've already chosen the best response.0thanks so much, i wasn't sure if i could just multiply 2 by 60, or if i had to use the identity 2tanx/1tan^2x

Best ResponseYou've already chosen the best response.1as long as the 2 and x are together you are fine tan(2x)

Best ResponseYou've already chosen the best response.0what if it's tan2x? it didn't necessarily specify tan(2x)

Best ResponseYou've already chosen the best response.1That is fine also if the 2 was outside for example 2tan(x) then it would be different
