WebThe direction cosines are also represented by l, m, n and we often represent the direction cosines as l = a √a2+b2+c2 a a 2 + b 2 + c 2, m = b √a2+b2+c2 b a 2 + b 2 + c 2, n = c √a2+b2+c2 c a 2 + b 2 + c 2. Here we consider l = Cosα, m = Cosβ, n = Cosγ. Hence we have the relationship between the direction cosines as l 2 + m 2 + n 2 = 1. chs hemophiliaWebSolution The cartesian equation of the given line is 4 − x 2 = y 6 = 1 − z 3 It can be re-written as x − 4 − 2 = y − 0 6 = z − 1 − 3 This shows that the given line passes through … description of a cat creative writingWebWhen we talk about a unit vector, we are talking about a vector whose magnitude is 1 in a given direction.
