# Circle:It will make you turn around!

Consider a circle \(x^{2}+y^{2}+ax+by+c=0\) lying completely in first quadrant. If p and q be the minimum and maximum value of \(y/x\) for all ordered pairs \((x,y)\)on its circumference .Then: \(p+q= \zeta ab/b^{\eta} + \theta c \) Find \(\zeta \eta \theta -9\)
