What Is Section Formula

The section formula helps in determining the coordinates of a point which facilitates division of the line joining two points in a ratio.

What is section formula. Bp m. The point p which divides the line segment joining the two points a x1 y1 and b x2 y2 internally in the ratio l. Then the point p divides segment ab internally in the ratio m.

The section formula enables us to find the co ordinates of a point if the ratio of the internal distances of any two points from the given point is given. Here h k 0. We use the section formula to find the point which divides the line segment in a given ratio.

Consider two points p x1 y1 and q x2 y2. It is often reported using y c where c is the distance from the neutral axis to the most extreme fibre as seen in the table below. To begin with take a look at the figure given below.

It locates the point dividing the line segment in any desired ratio. Find an equation of the circle with centre at 0 0 and radius r. The section formula tells us the coordinates of the point which divides a given line segment into two parts such that their lengths are in the ratio m.

This takes place either internally or externally. We can divide the line segment joining the points p and q by a third point r in two ways. And p be a point on the segment joining a and b such that ap.
