Question

Find tan θ if sec θ = sqrt 10/ 3 and sin θ < 0.

Answer 1

y = sqrt(10 + 3^2) = sqrt19
the angle is in 4th quadrant because sec is positive and sin negative
can you continue?

Answer 2

yeah i did all of that, i was only confused because my answer choices are
-3
3
-1/3
- sqrt 10

Answer 3

oopps sorry y = sqrt ( 10 - 3^2) = 1

Answer 4

oh okay i get it now

Answer 5

-1 not 1
and tan = -1/3

Answer 6

thanks

Answer 7

got there eventually - welcome
