Section FormulaLet A and B be two points in the plane of the paper as shown in fig. and P be a point on the segment joining A and B such that AP : BP = m : n. Then, the point P divides segment AB internally in the ratio m : n.If P is a point on AB produced such that AP : BP = m : n, then point P is said to divide AB externally in the ratio m : n.The coordinates of … [Read more...] about Section Formula
