Perpendiculars to two vectors So this is more than likely a simple question that has been asked before, but if have 2 lines described by the formula:
$V = (x,y,z) + L (i,j,k)$
i.e.  a line described by a position and a length along a unit vector
How would I find the line that is perpendicular to both lines?

Hint: Take the cross product.First write each in the form (a,b,c) by choosing t equal 0 and 1.
