Question 332989: if sin A >0 and tan A < 0, then A is in which quadrant?
Answer by AAfter.Com(18) (Show Source):
You can put this solution on YOUR website! Since sin A > 0, therefore, A is in either first or second quadrant.
Again, tan A < 0, therefore, A is in either second or fourth quadrant.
Hence, from the above two conditions,
it is concluded that A is in second quadrant.
