Hello aspirant,

Here are 3 important questions:-

Q. 1: Find the direction cosines of the line passing through the two points (– 2, 4, – 5) and (1, 2, 3).

Q. 2: Show that the points A (2, 3, – 4), B (1, – 2, 3) and C (3, 8, – 11) are collinear.

Q. 3: If a line makes angles 90°, 135°, 45° with the x, y and z-axes respectively, find its direction cosines.

you may prepare these questions but you should also have a look to other questions also.

Hope this helps you
