Let A(2, 1, -3) and B(5, -8, 3) be two given points. Find the coordinates of the point of trisection of the segment AB.

The coordinates of point R that divides the line segment joining points P (x1, y1, z1)


and Q (x2, y2, z2) in the ratio m: n are



Point A( 2, 1, -3 ) and B( 5, -8, 3 ), m and n are 2 and 1 respectively.


Using the above formula, we get,




( 4,-5, 1), is the point of trisection of the segment AB.
