" If two different tangents of "y^(2)=4x" are the nesmals to "x^(2)=4" by then "

If two different tangents of y^(2) = 4x are the normals to x^(2) = 4 by then :

If two different tangents of y^(2)=4x are the normals to x^(2)=4by, then (a) |b|>(1)/(2sqrt(2)) (b) |b| (1)/(sqrt(2))(d)|b|<(1)/(sqrt(2))

If two different tangents of y^2=4x are the normals to x^2=4b y , then

If two different tangents of y^2=4x are the normals to x^2=4b y , then

If two different tangents to y^2=4x are the normals to x^2=4 by, then

If two different tangents of y^2=4x are the normals to x^2=4b y , then (a) |b|>1/(2sqrt(2)) (b) |b| 1/(sqrt(2)) (d) |b|<1/(sqrt(2))

If two different tangents of y^2=4x are the normals to x^2=4b y , then (a) |b|>1/(2sqrt(2)) (b) |b| 1/(sqrt(2)) (d) |b|<1/(sqrt(2))

Two perpendicular tangents to y^(2)=4 a x always intersect on the line
