Tīmeklis2024. gada 4. maijs · Given direction ratios: 4, 2, and -4. The formula for directional cosines from direction ratios is given by, l =, m = and n = Here, a = 4, b = 2 and c =-4. l = , m = and n = l = \frac {4} {\sqrt {36}} m = n = Question 4: Let’s say we have a line with direction ratios 0, 1, 0. Calculate the direction cosines for the line. Solution: Tīmeklis2024. gada 28. nov. · Then we have x, y and z, all in terms of k and we can easily find their ratio. x = k/3 y = k/4 z = k/7 Since x, y and z all need to be integer, k/3 should be an integer so k should have 3 as a factor. k/4 should be an integer so k should have 4 as a factor. k/7 should be an integer so k should have 7 as a factor.
