CBSE Class 12 Mathematics 2026 Main Paper 65/2/1 · Question 15 (Three Dimensional Geometry)

Find the direction cosines of (2x−1)/4=(1−y)/3=−z/6 in the orientation given by increasing common parameter.

✅ Step-by-Step Solution

Final Answer: (2/7,−3/7,−6/7)
  1. The common parameter gives direction ratios (2,−3,−6), whose length is 7. Divide each ratio by 7.
