Question

What is formula of section formula?

Answer 1

Hii friend,

The section formula gives the coordinates of a point which divides the line joining two points in a ratio, internally or externally. P ( x , y ) = ( c ⋅ m + a ⋅ n m + n , d ⋅ m + b ⋅ n m + n ) .

Answer 2

Section formula for external division:

The coordinates of the point $P(x, y)$ which divides the line segment joining the points $A( x_{1}, y_{1})$ and $B( x_{2}, y_{2})$, internally, in the ratio $m_{1} : m_{2}$ are

$P(x, y) = [\frac{(m_{1} x_{2} + m_{2} x_{1})}{m_{2} + m_{1} }, \frac{(m_{1} y_{2} + m_{2} y_{1} )}{m_{2} + m_{1}}]$
