Find the direction cosines of z-axis.

1.	Find the direction cosines of z-axis.
Answer» We know z axis makes an angle 90° with the x axis and y axis and makes an angle 0° with z axis itself. So the dcs of z axis are (cos90°, cos90°, cos0°) = (0,0,1). Solution We know z axis makes an angle 90° with the x axis and y axis and makes an angle 0° with z axis itself. So the dcs of z axis are (cos 90°, cos 90°, cos 0°) = (0,0,1).

Answer»

We know z axis makes an angle 90° with the x axis and y axis and makes an angle 0° with z axis itself.

So the dcs of z axis are (cos90°, cos90°, cos0°) = (0,0,1).

Solution

We know z axis makes an angle 90° with the x axis and y axis and

makes an angle 0° with z axis itself.

So the dcs of z axis are (cos 90°, cos 90°, cos 0°) = (0,0,1).
