Question

What is dividing internally and externally?

Answer 1

Dividing an interval AB internally in a given ratio produces a point between A and B. External division produces a point outside the interval AB. In general, suppose that P(x,y) is on the line AB but is external to the interval AB and that APPB=k1, for some k>0.
