单词	external division(of a segment)
释义	external division(of a segment) Mathematics Let AB be a line segment. Then the point E is the external division of AB in the ratio 1: k if $k \vec{A E} = \vec{B E}$ where $\vec{A B}$ is the vector from A to B. If A and B have position vectors a and b, from some origin, then the position vector of E is $e = \frac{k a - b}{k - 1},$ sometimes referred to as the section formula. Compare internal division.
