Thank you Mr Brown

Guys,for the CIE 9231 syllabus,it’s better to remember and use the formula D=( (a1-a2)•(B1 X B2) )/|B1 X B2|,where Bs are the parallel vectors and As are the point.

Got my further maths exam tomorrow this will be helpful!

Thank you

Nice!

[@homunculus3646]

does it mean anything geometrically when you get values of λ and µ without simultaneous equations or is it just random?

[@ozairahmed1352]

The equation for distance between skew lines is in the formula book. i dont really understand it but would you recommend using this method or the equation in the formula book?

[@destined0645]

Is it needed that we use the general formula for both a and b instead of using a position vector and a general formula, like how we did to find the shortest distance between two parallel lines ?

[@jasonjebaraj6264]

Why would the shortest line that connects both lines together be perpendicular?
