Ex 10.2, 11 (Method 2) Show that the vectors 2๐ ฬ โ 3๐ ฬ + 4๐ ฬ and โ 4๐ ฬ + 6 ๐ ฬ โ 8๐ ฬ are collinear.๐ โ = 2๐ ฬ โ 3๐ ฬ + 4๐ ฬ ๐ โ = โ4๐ ฬ + 6๐ ฬ โ 8๐ ฬ Two vectors are collinear if their directions ratios are proportional ๐_1/๐_1 = ๐_2/๐_2 = ๐_3/๐_3 = ๐ 2/(โ4) = (โ3)/6 = 4/(โ8) = (โ1)/2 Since, directions ratios are proportional Hence, ๐ โ & ๐ โ are collinear
