Question

.(1) Prove sections formula.​

Answer 1

Step-by-step explanation:

We will proof the definition of section formula.

Section of a Line Segment.

Let AB be a line segment joining the points A and B. ...

Then, we can say that P divides internally AB is the ratio λ : 1.

Note: If AP : PB = m : n then AP : PB = mn : 1 (since m : n = mn : nn.

Answer 2

Answer:

Proof for Sectional Formula:

Let P(x1, y1) and Q(x2, y2) be two points in the xy – plane. Let M(x, y) be the point which divides line segment PQ internally in the ratio m : n. PA, MN and QR are drawn perpendicular to x- axis. PS and MB are drawn parallel to x – axis.
