    Thank you sir, just one little feedback.....i kindly request you to increase your mic volume because even with full volume it's barely heard.

    Sir I have also seen a different form like this:
    x-x1/l = y-y1/m = z-z1/n
    Where l, m , n are the direction cosines of the line
    But I don't know how did we get those I mean the actual equation has direction ratios of parallel vector in the denominator
    a = l * magnitude of parallel vector
    But in the book it has knly written l , m , n which are not equal to direction ratios a b c of the parallel vector

      Yes what you said that's right we prove by using direction cosines every line as a set direction cosine and infinity many direction ratios

      @@hrmsmathclass no, you didn't understand my question
      If you have the ncert book of math you can see that in the topic "Equation of line from a given point and parallel to a vector"
      There they have derived the Cartesian/symmetric form from the vector form
      And it is like this:
      x-x1/a = y-y1/b = z-z1/c
      Where a, b, c are the direction"ratios" of the "parallel vector"
      However after the derivation it has written another way of this form with direction "cosines" of the "line" l, m, n in the denominator
      Like this:
      x-x1/l = y-y1/m = z-z1/n
      Even though
      a ≠ l, b ≠m, c ≠n
      It is only possible if the magnitude of parallel vector is one
      There is not much information available in the book and even in the internet
