The output y is the area under a line given by two points p1, p2 which are assumed to be either both above or both below the abscissa, i.e., the ordinates of the points have the same sign.

Syntax

Functions.areaLineSegment(p1, p2);

Implementation

y := abs((p2[1] - p1[1]) * (p1[2] + p2[2]) / 2);

Examples

areaLineSegment({1,1},{2,1}); // 1.0
areaLineSegment({1,1},{2,2}); // 1.5

y = areaLineSegment(p1, p2)

p1	Type: Real[2]
p2	Type: Real[2] Description: Points whose ordinates have the same sign

y	Type: Real Description: Area between the abscissa and the line within the closed interval [p1[1], p2[1]]
