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 alphain[pi//4,pi//2] with the positive direction of the x-axis, then find the maximum length of this focal shord.

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 line makes an angle (pi)/(4) with the positive directions of each of X-axis and Y-axis, then the angle that the line makes with the positive direction of the Z-axis is

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

If a line makes an angle of pi/4 with the positive directions of each of x-axis and y-axis, then the angle that the line makes with the positive direction of the z-axis is (1) pi/6 (2) pi/3 (3) pi/4 (4) pi/2

Show that the focal chord, of parabola y^2 = 4ax , that makes an angle alpha with the x-axis is of length 4a cosec^2 alpha .

The length of a focal chord of the parabola y^(2)=4ax making an angle theta with the axis of the parabola is (a>0) is:
