Best ResponseYou've already chosen the best response.1since they are in 3d space; they can look to cross, but actually never touch. such as the line in the ceiling and the line on the floor both make it to a corner but never intersect each other

Best ResponseYou've already chosen the best response.0i can get the second equation in terms of x y and z but how do i sub that in to the second equation and how do i deal with t(2,4,5) ? !

Best ResponseYou've already chosen the best response.1we prove it by seeing if the scalar for one line vector equates to the scalar in the other ... but i gotta review it real quick to recall some details

Best ResponseYou've already chosen the best response.0hmm but how did you get that parametric equation ... you just diregarded x y etc?

Best ResponseYou've already chosen the best response.1now we equate our x=x but use a different variable to indicate our scalar; say s instead of t and solve for the system of equations

Best ResponseYou've already chosen the best response.1if the system of equations creates s and t to meet at a common point; then they intersect there; if not then they never meet
