j.l Posted April 3, 2014 Report Share Posted April 3, 2014 (edited) Sean las rectas L1 : P = (3,4,0)+r(1,2,-1) y L2: Q = (1,1,1)+s(1,0,2).Hallar la ecuacion de una recta que corta a L1 en A , a L2 en B y al eje X en C , de modo que AB=BC.

ingmarov Posted April 7, 2014 Report Share Posted April 7, 2014 (edited) Lx : (-1/2,0,0) +t(5/4,1,1/2) Se intersecta con L2 cuando t=1 y s=-1/4 Se intersecta con L1 cuando t=2 y r=-1 Y con el eje x obviamente en x = -1/2 cuando t = 0 Edited April 8, 2014 by ingmarov Link to comment Share on other sites More sharing options...
