Tangents are drawn from the point (4, 2) to the curve `x^(2)+9y^(2)=9`, the tangent of angle between the tangents :

If two tangents are drawn from a point on x^(2)+y^(2)=16 to the circle x^(2)+y^(2)=8 then the angle between the tangents is

If two tangents are drawn from a point on x^(2)+y^(2)=16 to the circle x^(2)+y^(2)=8 then the angle between the tangents is

Two tangents are drawn from the point (-2,-1) to the parabola y^(2)=4x .If theta is the angle between these tangents,then the value of tan theta is

Two tangents are drawn from the point (-2,-1) to the parabola y^(2)=4 x . If alpha is the angle between these tangents, then tan alpha=

Two tangents are drawn from a point (-2, -1) to the curve y^(2)=4x . If alpha is the angle between them, then |tan alpha| is equal to :

Two tangents are drawn from a point (-2,-1) to the curve y^(2) =4x, If alpha is the angle between them , then | tan alpha | is equal to
