Vector and Parametric Equations of a Line (Line in 3 dimensions)

In this video we derive the vector and parametic equations for a line in 3 dimensions. We then do an easy example of finding the equations of a line.

    Sometimes, a small example with a picture is better than dozens of pages of proofs and theorems.

    Out of 3-4 videos I watched, this guy actually explained why we first must find a vector r to define the line l. Good job for actually teaching things well man, and thanks for the video.

    This video was absolutely perfect. It was EXACTLY what I was looking to understand. My textbook (for vector calc) just gave us the definitions for the equation of a line in point direction form, threw in a graph, and expected us to be able to figure it out. Thank you, thank you. Your explanation was succinct and clear. I will probably end up watching many more rootmath videos after this one.

    This is the best explanation of the vector form of a line I have seen so far. I have been trying to understand it for a long time. Some video I've watched was drawing parallels between vector form o a line and linear function which was quite confusing for me. Your teaching style facilitate learning by a big measure. Thank you!

    The best interpretation of line equation in vector form. The essential plays behind the equation is position vector that knowing the position vector is equivalent to knowing the coordinate of the line.

    I came here only becouse I know a youtuber that studies this topic at school in calculus. I just wanted to say that here in Italy (at least at the school I went in) we didn't discuss this topic, which is still a good one as a precourse for a uni physics course. We instead studied the equation of a line in a 2 dimension cartesian plane and other geometric figures again in 2d and that's it. We never discussed the 3d plane, but after seeing this video, I wish we did. Good luck with school from Italy ;)

    Additional notes: The vector ''d'" need not be on the line.It is just any vector at any point in space to which the line "l" is parallel.You choose vector 'r' as any point on 'l' and make vector r - r(sub0) = t.d [ 't' times vector 'd' ]where t is a variable rational number.This provide the vector equation.

    Wonderful tutorial. Have a question: many other tutorials require 2 points to get the 3d equation of the line in vector and parametric form. Here instead you require a point and a direction vector. Can you expand on this all?

  • @rootmath

    @rootmath

    6 жыл бұрын

    Two points will give you a direction vector since P1 - P2 = d is the direction between P1 and P2. Since you have 2 points you also, obviously, have 1 point. Thus 2 points is sufficient to find the equation of the line. Still though it is useful to think of a point and a direction as the minimal information you need.
