I find students encounter difficulties in resolving vectors into the components, especially when the axis is tilted or rotated. The following are some steps which I find useful to emphasize to them:

- Draw the axis. Without drawing the axis, it is difficult to find the components on the axis. So always draw the axis.
- Draw a rectangle with a diagonal line, and follow this criteria: (a) The vector we want to resolve is the diagonal line, (b) The sides of the rectangle must coincide with the axis.
- Indicate the known angle.
- Use TOA CAH SOH to determine which trigonometric functions to use.
