Calculus 3: Integration - Equations of Lines & Planes (8 of 27) Determine If the Lines Intersect

In this video I will determine is 2 lines (expressed in parametric equations) in 3-D space intersect each other.

Next video in the series can be seen at:

Thank you. I was searching all over the internet and everyone made it sound so much more complicated! You helped me see I was on the right track before I started looking for help too.

My thought was in the same way that in the previous video you determined how to tell if the lines are parallel, we do this. So baiscally see if the t and s lines are multiple of one an other. If they are the are parallel if not they intersect.

thank you so much for this simple yet informative explanation! really saved me this time!!

True or false; Any 2-D lines that are not parallel to each other intersect at some point? Is my statement correct?

[ssemakulagraceernest]

the challenge is that its only parallel lines that do not intersect
