Focal chord of parabola formula
WebParabola is a set of all points in a plane that are equidistant from a fixed point and a fixed line. The fixed point is called the focus, and the fixed line is called directrix.The turning point is called vertex which is equidistant from the focus and the directrix FOCUS – is the fixed point that is used to define the parabola with the fixed line. VERTEX – is the turning … Web∴ Equation of focal chord is ... The length of a focal chord of the parabola y 2 = 4 a x making an angle with the axis of the parabola is. Medium. View solution >

WebLength of Focal Chords. LENGTH OF ANY FOCAL CHORD: Through a point t, a focal chord is drawn in the parabola y2 = 4ax y 2 = 4 a x . The other end-point of this chord is, as described earlier, − 1 t. − 1 t. … The chord of the parabola which passes through the focus is called the focal chord. Any chord to y2 = 4ax which passes through the focus is called a focal chord of the parabola y2= 4ax. Let y2= 4ax be the equation of a parabola and (at2, 2at) a point P on it. Suppose the coordinates of the other extremity Q of … See more The combined equation of straight line y = mx + c and parabola y2= 4ax gives us the co-ordinates of point(s) of their intersection.
