Direction Cosines

### Interactive Graph

Use the Interactive diagram given below to see the direction cosines of a vector with x, y , z and all three axis in three dimensional view.

• Go Back to Default View: You may move the coordinate system back to the default view.
• Start / Stop rotating the View Automatically
• Adjust the View Direction: You may choose between the view towards the xOy-plane, xOz-plane, yOz-plane,
• rotate back to the default view.

1. Direction cosine of a vector with x axis.

Hold and drag the point ‘p’ Horizontally and vertically to adjust the position vector of ‘P’ and observe the angel it make with x – axis.

2. Direction cosine of a vector with y axis.

Hold and drag the point ‘p’ Horizontally and vertically to adjust the position vector of ‘P’ and observe the angel it make with y – axis.

3. Direction cosine of a vector with z axis.

Hold and drag the point ‘p’ Horizontally and vertically to adjust the position vector of ‘P’ and observe the angel it make with z – axis.

3. Direction cosine of a vector

Hold and drag the point ‘p’ Horizontally and vertically to adjust the position vector of ‘P’ and observe the angel it make with all three axes.
