x ^(2) +y ^(2) =a ^(2) is the standard equation of a circle centred at (0,0) and radius is a. Paramatric Equation to Standard Circle: Parametric Equation for the circle x^(2) +y ^(2) =a ^(2) is x =a cos theta, y =a sin theta. Director Circle: Director circle is the locus of point of intersection of two perpendicular tangents. Two points A (-30^(@)) and B (150^(@)) lies on circle x ^(2) +y ^(2) =9. The point (theta) which moves on a circle such that area of Delta PAB is maximum, is/are

x ^(2) +y ^(2) =a ^(2) is the standard equation of a circle centred at (0,0) and radius is a. Paramatric Equation to Standard Circle: Parametric Equation for the circle x^(2) +y ^(2) =a ^(2) is x =a cos theta, y =a sin theta. Director Circle: Director circle is the locus of point of intersection of two perpendicular tangents. A ray of light which comes from (-3,1) travels along a line L and after reflection from the circle x ^(2) +y ^(2) =a ^(2), reficated ray moves along the same line L, then the equation of line L is
