Question

If sin Θ = 1 over 3 and tan Θ < 0, what is the value of cos Θ

Answer 1

sin^2 + cos^2 = 1

Answer 2

\[\tan \theta =\frac{ \sin \theta }{ \cos \theta}\]

Answer 3

\[\sin \theta= \frac{ 1 }{ 3 }\]

Answer 4

use above 2 formula to find tan

Answer 5

@nbudel from the figure find the value of cos theta
