Tangent are drawn from the point `(-1,2)` on the parabola `y^2=4x` . Find the length that these tangents will intercept on the line `x=2.`

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

Tangents are drawn from the point (-1,2) to the parabola y^(2)=4x. These tangents meet the line x=2 at P and Q, then length of PQ is

Tangents are drawn from the point (-1,2) to the parabola y^(2)=4x The area of the triangle for tangents and their chord of contact is

The angle between the tangents drawn from the point (1,4) to the parabola y^(2)=4x is

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