Question
If tan θ = - 
, then sin θ is
, then sin θ isOptions
A.
but not 
but not B. or
or C. but not
but not D.None of these
Solution
Since, tan θ < 0
∴ Angle θ is either in the second or fourth quadrant.
Then, sin θ > 0 or < 0
∴ sin θ may e or
∴ Angle θ is either in the second or fourth quadrant.
Then, sin θ > 0 or < 0
∴ sin θ may e
