You can put this solution on YOUR website!
If tan(theta) < 0, then theta is an angle whose terminal arm is in quadrants;
\n" ); document.write( "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.
\n" ); document.write( "------------------------------------------------------------------
\n" ); document.write( "Ans: theta is in Q II or in Q IV
