Given #tanx=5/12, secx=13/12# to find the remaining trigonometric function? Trigonometry Right Triangles Relating Trigonometric Functions 1 Answer Nghi N. Mar 27, 2017 #sec x = 1/(cos x) = 13/12# --> #cos x = 12/13# #tan x = 5/12# #sin x = tan x.cos x = (5/12)(12/13) = 5/13# #cot x = 1/(tan x) = 12/5# #csc x = 1/(sin x) = 13/5# Answer link Related questions What does it mean to find the sign of a trigonometric function and how do you find it?
