Question

let theta be angle in quadrant II such that sec(theta)=-10/7. Find the exact values of cot(theta) and sin(theta)

Answer 1

1+tan^2theta=sec^2theta
tantheta=1/cottheta

Answer 2

I have \[\cot \theta=\frac{ 7 }{ \sqrt{51} }, \sin \theta=-\frac{ 51 }{ 10 }\]

Answer 3

@rvc is that right?

Answer 4

cot correct

Answer 5

\[\sin \theta should be -\frac{ \sqrt{51} }{ 10 }\]

Answer 6

cot is minus and sin is correct

Answer 7

good!!
