The normals are drawn from `(2lamda,0)` to the parabola `y^2=4x` .Show that `lamda` must be greater than 1. One normal is always the X-axis. Find `lamda` for which the other two normals are perpendicular to each other.

Three normals are drawn from the point (c,0) to the curve y^2=x . Show that c must be greater than (1)/(2) . One normal is always the X-axis. Find c for which the other two normals are perpendicular to each other.

Three normals are drawn from the point (c,0) to the curve y^2=x . Show that c must be greater than 1/2 . One normal is always the x-axis. For what values of c are the other two normals perpendicular to each other
