Ex 11.2, 1 Find the coordinates of the focus, axis of the parabola, the equation of directrix and the length of the latus rectum for y2 = 12x Given y2 = 12x Since the above equation is involves y2 Its axis is x-axis Also coefficient of x is positive (+12) Hence we use equation y2 = 4ax Latus Rectum is 4a = 4 × 3 = 12
