Best ResponseYou've already chosen the best response.1ok, imagine you have a 30 60 90 triangle dw:1358813789639:dw cos(30) = sqrt(3)/2 inverse cos (30) = 1/cos(30) 1/cos(30) = 1/(sqrt(3)/2)) 1/cos(30) = 2/(sqrt(3))

Best ResponseYou've already chosen the best response.1cos(30) = 2/sqrt(3) inverse cos (30) = 1/cos(30) 1/cos(30) = 1/(2/sqrt(3)) 1/cos(30) = (sqrt(3)/2))

Best ResponseYou've already chosen the best response.1actually x= 30. cos(30) = 2/(sqrt(3)) and cos^1(30) = sqrt(3)/2
