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?
