Focal chord
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 the … 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. The … See more Equation of the chord of the parabola y2 = 4ax whose middle point is (x1, y1) is (y-y1) = 2a/y1(x-x1) This can be written as T = S1, where T = yy1 – 2a(x+x1) and S1 = y12 – 4ax1. See more Consider the parabola y2= 4ax. If (x1, y1) is a given point and y12– 4ax1= 0, then the point lies on the parabola. But when y12– 4ax1≠ 0, we draw the ordinate PM meeting the curve in L. Then P will lie outside … See more WebFocal Chords offers original songs and music free for listening, downloading and sharing Listen to our music!
