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
