Given #tanx=sqrt3/3, cosx=-sqrt3/2# to find the remaining trigonometric function? Trigonometry Right Triangles Relating Trigonometric Functions 1 Answer Gerardina C. Jan 10, 2017 #sinx=-1/2# #cotx==sqrt(3)# #secx=-2/3sqrt(3)# #cscx=-2# Explanation: Since #tanx>0 and cosx<0#, since #tanx=sinx/cosx#, it is sinx<0. Then #sinx=color(red)-sqrt(1-cos^2x)=-sqrt(1-(-sqrt(3)/2)^2)=-sqrt(1-3/4)=-1/2# #cotx=1/tanx=3/sqrt(3)=sqrt(3)# #secx=1/cosx=-2/sqrt(3)=-2/3sqrt(3)# #cscx=1/sinx=-2# Answer link Related questions What does it mean to find the sign of a trigonometric function and how do you find it?
