If sin x = 1/3 and x is in quadrant III. How do I find cosx, tanx, cotx, secx, and cscx? the negative sign is throwing me off.

Best ResponseYou've already chosen the best response.0Steps: 1) draw a triangle 2) sinx = opposite/hyp so your hyp. = 3 then use this rule to find the last side: \[c^2=x^2+y^2\] 3) cosx = adj/hyp 4) tanx = sinx/cosx 5) cotx = 1/tanx 6) secx = 1/cosx 7) cscx = 1/sin x ^_^ give it a try

Best ResponseYou've already chosen the best response.0yep ^_^ now all you have to do, is plug in the right sides in the following trigs :)

Best ResponseYou've already chosen the best response.0cos= √8/3 tan =1/√8 cot=√8 sec= 3√8/8 csc = 3 are those right? I don't think they are

Best ResponseYou've already chosen the best response.0tan is wrong, tanx = sinx/cosx = (1/sqrt(8)) sec is the inverse of cos x ^_^ and csc is the inverse of sinx :) so secx = sqrt(8) /3 ^_^

Best ResponseYou've already chosen the best response.0positive because x = positive and hyp = positive ^_^

Best ResponseYou've already chosen the best response.0if it is in the third quadrant then both sin x and cosx = negative and tan x = positive
