1.	If the angle of intersection of the circles x2+y2+x+y=0 and x2+y2+x−y=0 is θ, then equation of the line passing through (1,2) and making an angle θ with the y − axis is
Answer» If the angle of intersection of the circles $x^{2} + y^{2} + x + y = 0$ and $x^{2} + y^{2} + x - y = 0$ is $θ$ , then equation of the line passing through $(1, 2)$ and making an angle $θ$ with the y − axis is
