If a focal chord of `y^2=4a x` makes an angle `alpha in [0,pi/4]` with the positive direction of the x-axis, then find the minimum length of this focal chord.

If a focal chord of y^(2)=4ax makes an angle alpha in[0,(pi)/(4)] with the positive direction of the x- axis,then find the minimum length of this focal chord.

If a focal chord of y^(2)=4ax makes an angle alphain[pi//4,pi//2] with the positive direction of the x-axis, then find the maximum length of this focal chord.

If a focal chord of y^(2)=4ax makes an angle alphain[pi//4,pi//2] with the positive direction of the x-axis, then find the maximum length of this focal shord.

If a focal chord of y^(2)=4ax makes an angle alphain[pi//4,pi//2] with the positive direction of the x-axis, then find the maximum length of this focal shord.

If a focal chord of y^(2)=4ax makes an angle alphain[pi//4,pi//2] with the positive direction of the x-axis, then find the maximum length of this focal shord.

A focal chord of the Parabola y^(2) = 4x makes an angle of measure theta with the positive direction of the X - axis . If the length of the focal chord is 8 then theta = . . . . ( 0 lt theta lt (pi)/(2))

The length of the focal chord which makes an angle theta with the positive direction of x -axis is 4a cos ec^(2)theta

If a normal chord of the parabola y^(2)=4x makes an angle of 45^(@) with the axis of the parabola then its length is
