Question

Find the distance between the skew lines L1: x=y=z and L2: x+1=1/2y=1/3z

Answer 1

we need a line that is perp to both of them, so cross their direction vectors is my first idea

Answer 2

what would be the parametric equation for line2?

Answer 3

these are formated such that t = ....

line 1
x = y= z = t

x = 0+t
y = 0+t
z = 0+t

line2
x+1=1/2y=1/3z = t

x+1 = t ; x = -1+t
1/2 y = t ; y = 0+2t
1/3 z = t ; z = 0+3t

Answer 4

thank you . i got it from here
