Best ResponseYou've already chosen the best response.1yes that's right i like degrees if you like it too then you can convert radians to degrees \[\huge\rm \frac{ 5\pi }{ 6 } \times \frac{ 180 }{ \pi }\]

Best ResponseYou've already chosen the best response.1and if you look at the unit circle 5pi/6 is heredw:1433434723738:dw and you need signs of cos sin and tan values for that just remember CAST rule or it is like normal x y graph
