Question 180098: If tan 0<0, then 0 is an angle whose terminal arm is in quadrants;
1 or 3
2 or 4
3 or 4
4 or 1
Answer by stanbon(75887) (Show Source):
You can put this solution on YOUR website! If tan(theta) < 0, then theta is an angle whose terminal arm is in quadrants;
Since tan = y/x, the y and the x must have opposite signs when tangent is negative. That is the case in the 2nd and in the 4th quadrants.

Ans: theta is in Q II or in Q IV
